Obviously the most effective way to fight fascism is to elect fascist government and wait until fascists show their incompetence as a governing party, while established institutions and system of checks and balances is ensuring the integrity of next elections, so the fascists will be gone once and for all after a single term.

You can use whatever words you want to describe it, but at the end of the day when we have the majority of the population voting for something you don't want, you're the minority. Trying to fight against the rights of the majority of the population is a dangerous battle only previously tried by authoritarian dictatorships and similar regimes.

No one seriously tried to stop these people from becoming candidates, but now they have support of the public the ruling powers oppose them.

Also worth mentioning, in Romania, political left and rights seem to be flipped. Far right wing candidates want more rights for gays, etc. So can get confusing depending on which media sources are used.

Sounds great until you remember that the current governments of Romania, Germany, France, Britain, etc. are all arming and funding Nazis in Ukraine and enabling ethnic cleansing by a genocidal apartheid occupation regime in Palestine.

it can not be allowed for groups that espouse extreme ideologies to even gather the smallest of support

but it can be allowed to give billions of Euros and tons upon tons of weaponry to swastika-tatooed Hitler worshippers bent on ethnic cleansing. It can be allowed to prop up a corrupt, kleptocratic, dictatorial regime that has cancelled elections, placed all media under state control, declared WW2 Nazi collaborators to be their national heroes, imprisons, tortures and brutally murders journalists, political opposition, people who make online posts against the government or the war, and people who just don't want themselves or their relatives be forcibly drafted into a war against their own brothers. That can be allowed, right?

Personally i just find it extremely hypocritical to constantly talk about how much Europe loves democracy and at the same time steal an election from the candidate who was about to win it and then go on to ban that candidate, who is clearly polling far ahead of all others, from standing in the repeat elections.

The reality is that these right wingers are not being banned from elections for their extremist views (which they undoubtedly hold, i'm not saying they don't), they are banned because they are anti-EU and want peace with Russia instead of war. That is the "extremism" that is intolerable to the Brussels bureaucrats and their comprador lackeys in the Romanian state. A leftist candidate with the same popularity and the same views toward the tyrannical EU and the self-destructive European drive to war against Russia would be treated exactly the same, if not worse.

Democracy as been shown, countless times, it is a very fragile system, vulnerable to players willing to manipulate and distort it in order to achieve personal gains, at the detriment of a large majority.

This has always been happening for as long as "liberal democracy" has existed. The worst offenders of manipulation and distortion of democracy are the mainstream media, who constantly manipulate public opinion in favor of the so-called "moderate" and "centrist" parties that have been getting elected for decades in Europe. This is also to the detriment of a large majority.

Or do you seriously believe that the policies of either the Tories or the Labor party in the UK have benefited the large majority in Britain? How about Macron in France, has he not been a detriment to the large majority of his citizens? So much so that the French voters overwhelmingly rejected his party (yet he somehow is still in charge...)? How about the SPD, CDU and Greens in Germany? How is it not to my detriment as a German citizen for them to cut social spending in favor of massive rearmament? How is it not a detriment to the large majority of Europeans for these parties to push us into a war with Russia? Why is that still allowed?

Why is it that it is not allowed to democratically vote for candidates who oppose the EU (which is a fundamentally neoliberal and highly undemocratic institution that makes it impossible for countries to have left wing economic policies and is now led by unhinged warmongering lunatics who want to pump hundreds of billons of Euros to their friends in the arms industry) and who want peace instead of war?

Giorgia Meloni in Italy is just as much a fascist sympathizer as these right wingers in Romania, but the reason why she was not treated this way is because she was willing to bend the knee to Brussels.
