That's cool, not everybody has to like free speech; defending free speech or not is purely a political opinion, like many other issues.
See, I'd be more impressed by the "we're just defending free speech" argument that comes up so often if it was ever for anything other than racism, sexism and hate.
It's also used for pornography, e.g. when Tumblr decided to clean their platform, the LGBT+ community seemed to be hit especially hard.
Upholding principles only count when it's uncomfortable. Otherwise they're not principles.
Of course the things getting pushed away are unpalatable, that's why they're targeted.
