Earlier quoted context omitted.
I was also curious about Parler but, when going to sign up, it asked for my phone number. Ummmm, no thank you. That kind of association is like going to a protest with your cellphone. Pretty easy to get the wrong kind of association attached to you.
Does your choice of words cause you to pause and think about where we are as a society? The "wrong kind of association" for creating a social media account?
Beyond that, if a platform is known for encouraging behaviour that you and your peers disapprove of. It might make sense for you to avoid registering there in case your peers get the wrong impression of you should the information leak. While not exactly social media, you only need to look at the fallout from Ashley Madison for why you might not want to sign up somewhere because of "the wrong kind of association".
Why social media would be the only forum exempt from this line of thinking I can't imagine.
