I think this person is heavily projecting or trolling to disrupt further conversation. They very clearly got what they wanted, probably an American liberal like they projected at me.

You cut off my sentence. Here's the full quote.

Their original comment absolutely did not imply they thought that it was only MAGAheads who were ok with Israel killing USAmericans, on the same level that you implied they thought that.

Whether or not there was an implication at all is subjective. I don't think that criticism of one party should be understood to be at the exclusion of another party, but whether or not that implication is there at all is up to you. I think making those sorts of inferences makes it very difficult to have any discussion about politics when criticising some group is meant as condoning another group; in that case any political statement would have to be very long to list all the groups it applies to.

But I didn't say that it wasn't implied at all; I said it wasn't implied at the same level. Your reply to the original comment would make no sense if you didn't believe that they only thought MAGA supporters were ok with Israel killing USAmericans. There's far more ambiguity in the original comment, and I don't believe it automatically lends itself to your interpretation (which was proven wrong by that commenter saying they don't believe such a thing), but in any case it is absolutely not the same level of implication as your comment.
