[apologies in advance for the long comment. Brevity is not my strong suit]

deadly serious, never seen a single one of them that wasn't just an anti-social weirdo.

Except anti social doesn't mean non religious or faking to be religious. They strike me as sheltered white men that grew up in a much more accelerated clown world than you or I might have grown up in. All I know is that I would be pretty fucked up and anti social if I had to go to high school in the 2010's. It seems like these guys might look awkward because they are probably very new to catholic trad beliefs. Catholic traditionalism and america first ideas that are expoused by the groypers is so radically different then how anybody really acts in 2020 that it's going to come off as awkward and disingenuous.

they're just incels who pretend that they're actually just too moral to have friends and a girlfriend

I think this is a great trend. I'd rather an alt right 'incel' that tries to follow some righteous religion path than going over to the left and becoming a degenerate. You also have to be very careful with the word 'incel' shareblue and many left wing propaganda outfits target right wing youth with this label (they've decided in their think tanks that it's an effective weapon against us). The reality is that many white men are only celibate because of the clown world sexual dynamics that are at play. Women aren't going after the top 20-30% of men they are going after the top 3% of men and young whites have more and more competition in addition to constant demoralization campaigns. Not to mention a world of advertisement and media that tell young women white men are worthless and that black men are masculine gods.

The legal system also does not tolerate young white men acting with any aggression that might attract females. Only blacks get to act with traditional masculine aggression. Whites are treated with a heavy hand by schools and police when they simply stand up for themselves or attempt to explore masculine aggression and assertiveness.

just too moral to have friends and a girlfriend

Ok. Still better than giving into clown world and just being a degenerate coomer. I don't see a lot of immoral young white guys doing significantly better with women in the sexual marketplace and when they do they often wind up with seriously fucked up women as a result of the party scene that had to sacrifice themselves too to get laid. I think these groypers our stumbling and trying to find a new path and since they line up with the dissident right on 90% of our issues and because they are young white men I strongly support them (as cringe as they may be).

so they just go around trolling people and acting like annoying little faggots.

Sounds like you simply have a grudge with these people. I don't really see the behavior you're describing. I'm also really skeptical with most online personalities. Someone could easily just be trolling and they aren't really a groyper at all. Maybe you are running into divide and conquer tactics?

im not sure what about this archtype is supposed to strike me as being genuinely christian, if that's what christianity is then consider me the antichrist.

This is where I take your side a bit more. These young men probably don't have a lot of experience with genuine traditional Christianity. I can say that with confidence because there just aren't a lot of genuine trad catholic masses and communities in the US. SSPX only has 600 some odd churches and the Russian orthodox church is small and insular. These young men are probably just realizing they they like the 'idea' of being a traditionalist but don't really have the opportunity to live it. Does that make them hypocrites? Maybe but that also makes the idealists and isn't that what we are as well? How many of us here wants an ethnostate or a secessionist movement or dixie dissident compounds or mannerbunds? Or freedom of association laws? Quite a few? How many of us are actually living those dreams? Not many. But that doesn't mean we stop and give up? Fuck no. You have to have something to strive towards. It's impossible to hit a target you haven't first conceptualized and then aimed at.
