This is an utterly bizarre chain of comments.
You quite literally stated that Political Twitter was isolated to "Extreme left authoritarian political opinions" prior to Musk's takeover. Which is of course both demonstratively false and a ridiculous claim on its face.
If anything, the person responding to you gave you the benefit of the doubt, presuming you may have meant that views outside the "extreme authoritarian left" were systematically de-emphasized by the recommendation algorithm. Which is also false but at least not a mindbogglingly stupid thing to actually believe.
Someone interested in an actual discussion might have taken the opportunity to clarify their initial statement. But abrasiveness and the "read what I meant, not what I wrote" approach also works I guess.
