The thing you backed up with hard evidence is that right-leaning folk were more targeted for censure.
Otherwise, we can compare all day hateful posts from Left types vs Right types and see who has the most...probably about even these days, tho' minus the bots I think the Left still edge it on Twitter.
Your first line is an absolutely mental take - you've taken your own idea and concept of "free speech" and applied it to a niche case. By your own definition, the right wing should be called nazis and all sorts every day, as they call LGBT people pedos and *cigarette-ends* every day.
Imagine saying in one post you want censure of racism/abuse and then saying it should've been allowed a post later with this one. They were targeted because of hate they say - they even made not one but about 5 other platforms to spout their abuse on. That was the whole point of Qanon, of the Trump social media, of the other one whose name I forgot (sorry about that) and so on - NO MODERATION.
I'd imagine if I started calling you a Nazi because (IIRC) you're of German descent (or are you German? Genuinely forgot, sorry!) I'd get rightly banned/punished. Would you then defend me as a courageous act of freedom of speech?
I've been around long enough to know you and your incessant arguing about your very own type of idyllic freedom of speech/acts, but what you keep saying isn't freedom of (in this case) speech - it's just allowing whoever's loudest under the pretense of "freedom of speech".
Point me in the direction of those incredibly abusive for no reason far lefters that, for no reason, attack the right by the way. Because the opposite exists and it's very, very loud and obvious. Somehow very coincidentally, also banned/punished everywhere but on Twitter. Wonder why that is?
