2/3fags have nothing to discuss unlike 4/5/1.
Also because they themselves don't try to find actual discussion beyond waifufagging and shitposting.
They don't try to argue their girl's case on the merit that their girls are diligently trying to make progress with Fuutaro and how that might overpower 5's 1st girl meta, 4's lolikanos, or 1's mix of both past and present.
They choose to fall back on muh parallels or completely bogus theories.
Also their waifufaggotry extends beyond just posting about their waifu or pics of them. It also includes shitting on other quints. That's why 2 & 3 shitposters attract each other. They love shitposting at each other. Not all 2/3fags are like that, but the shitposters go rampant while the good ones are rather quiet or just quit posting.
p.s. OP picked a shit topic so the thread has no direction and is shittier as a result.
