Well, that's certainly what the people telling you what they want you to believe want you to believe. People have been saying that all my life, and it wasn't any more true in the '70s for the Moral/Silent/whatever Majority than it is now.

HackerNews is at best center-left. Maybe not that.

The world extends beyond America where being on the "left" involves drone bombing.

the issue is the militancy, not the particular orientation.

i actively flag all political posts here. this is clearly not a place to have a sane political discussion .

I don't think discourse is hurt by quarantining r/the_donald. It has a tendency to show racist/misogynistic/conspiracy theorist memes and isn't really a good place at all for actual discourse.

Where did you get the idea most coders tilt far-left?

It is disingenuous to suggest that these subreddits are being banned simply because they "attack the left". T_D was banned because of a consistent pattern of rhetoric that violates Reddit's ToS, the most recent cases being outright calling for taking up arms against the government and killing police officers. r/frenworld, r/clownworld, and r/honkler were all banned for similar reasons, being hotbeds of violent white nationalist rhetoric.
