You "vehemently disagree" with the "Democratic Party line" that "speech is at the mercy of a handful of mega corporations with the ability to steer public opinion"?

That being the case...

I assume you must feel that speech is not threatened by the likes of Facebook and Twitter and thus you would certainly agree there would be no reason to regulate them. They should be free to exercise their corporate free speech rights to censure content for any reason or no reason at all. Right?
