I hate to see this strawman every single time there is an attack on free speech. You are actually mocking the fight for free speech. You aren't attacking the hypocrites that only use it when convenient.
The only purpose this rhetoric serves is to justify using the power of government to silence opponents the next time your side happens to be in power.
I think the ability for good concepts to be "tainted" by the opposition is the most dangerous manifestation of tribalism/group think, in modern society.
