Because you don't understand the concept of "free speech" as defined in the Constitution.
Twitter tried free speech and they got flooded with liars who slandered other members, con artists who used the site to fleece the gullible, and conspiracy theorists who spread disinformation about the government and everything else.
Twitter was forced to ban the liars, to restore some semblance of sanity to the site, as did Facebook.
The rest of your post is just the usual right wing lies about the left. Why are white males so insecure, and needy. Why can't you ever admit you're wrong, or you've behaved badly, or you've lost an election.
Why are you such weak ass, spineless wonders that you would elect a piece of shit like Donald Trump as President. You're problem is that you think Trump is some kind of hero, instead of the worst example of toxic masculinity you can find.
