I think liberals should take this as an opportunity to do a fact check on themselves. They are mostly right when they say they are loosing political terrain with Musk at Twitter.

I am m the opposite of a liberal, call it whatever you want. The Internet, media and corporate world is mostly always against my views. Guess what: I am still fine and believe it or not, despite two decades of massive liberal propaganda, my anti-liberal feelings are stronger than ever.

So if you are liberal you probably believe your side is the good one and can hold against facts, contradictions and fights. You should not be afraid of loosing some ground. If you are right, the stupid, opposite and wrong ideas of anti-liberals can't win. You are safe.

You seem to be afraid that allowing a bit of opposite speech will hurt your political stands. I would say: trust yourself, trust your beliefs and spread them intelligibly, and mostly, live by them.
