Not condoning bigotry, but it kind of sounds like you are saying you prefer echo chambers. It is healthy to see opinions you disagree with, even from bigots. Seeing opinions you disagree with allows for critical thinking about why you disagree. Even though ignorance is bliss, it is still ignorance.
I also think the sample size fallacy may come in to play here. i.e. comparison of billions of users (reddit) to tens of thousands (lemmy - post migration, if I understand correctly, previously lemmy was in the thousands user pre migration from reddit).
I think Twitter is dumb so I never had an "oh shit I also think Elon is dumb and need to leave" moment.
I now definitely relate to what people went through, as Reddit was my single online "social" presence, and I can't in good conscience continue to support them in any way, shape, or form because of the blatant shady attacks against developers.
All that aside, I am super impressed with lemmy (and the fediverse) and kind of bummed it took me until "the big migration" to look into it. I already prefer lemmy 1000% to Reddit after only a couple of days.
I would also MUCH RATHER donate to random cool folk keeping uptime on lemmy instances than, something like, pay reddit monthly for no ads.
