It's because we've reached a point where the average conservative rhetoric is toxic, harmful and generally flat out incorrect. Political lines are now about acknowledging facts or not, and being bigoted or not. Places like Bluesky that don't allow misinformation or bigotry are of course going to be harsh on the political party that thrives on both.

Yes, but not particularly.

> Political lines are now about acknowledging facts or not

Political lines are about which facts you accept. On many of the social issues of today, which are far more contentious than economic ones, liberal "facts" are often two lies and a half-truth wearing a trench coat. What liberals[1] want is a monopoly over which facts are on the table, and for all discussion to take place within that framing. And accusations of toxicity, harm, disinformation, and bigotry, are employed as rhetorical tools to preserve that monopoly.

[1]: By "liberals" here I don't mean average liberal voters, but politicians, pundits, influencers, and the class of affluent, politically-engaged people who tend to set the tone generally.
