So where does this leave us? Probably down a dark road. If someone disagrees with me, I won't fight for them to be banned. I might call them retarded, but that's another discussion.
He can go to Parler if he doesn't want to be on Twitter. He broke Twitter rules, repeatedly, and Twitter was giving him a lot of slack until they didn't. Would you argue that he shouldn't be banned if he came here and started spamming off topic nonsense all over the forum?
No he can't because Google have already taken it down from their playstore and Apple will most likely follow suit. Next step will be ISPs banning the host most likely if left wing voices still consider it a threat to their views.
Hardly a good comparison if he would join BitcoinTalk and spam threads. No one on this forum is (presumably) an elected president.
If words were ever that dangerous why is social media allowed to exist?
The guy that started Facebook started his social media career with a site stealing women's photos from a university index and allowing people to rate them.
To pretend such people somehow have the moral high ground is utter moronic.
