YouTube and Twitter are not government entities or government sponsored entities. Therefore, they are not creating a "public place" any more than the Holiday Inn is creating a public space when it offers a free Continental breakfast to its patrons. These for-profit companies are permitted to change the terms of their service agreements at their convenience and discretion. Because they are operating a business, they have the right (and perhaps even the economic incentive) to remove content deemed objectionable by a sizeable minority of their patrons, irrespective of the moral considerations involved. If you don't like YouTube's TOS, find an MRM-friendly commercial competitor, but arguing that YouTube is censoring free speech is misguided if you believe that companies, and people, should have the right to operate as they wish. Now, with respect to the subject of the false reports of "bullying" by feminists online, obviously it's a silencing tactic that I don't agree with, but I don't see how it is illegal. If anything, it helps the MRM by drawing attention to the two most critical flaws of feminism: its doctrinaire resistance to ideas that are contrary to its perceived wisdom and its top-down organizational structure, which makes it harder for the ideology to adapt to the much more fluid and dynamic conditions "on the ground," meaning on the base level of society where few class privileged feminists dare to tread. This is not just a criticism of feminism, by the way, but a criticism of academia in general. Was it Einstein who said it's better for students to be encouraged to question everything in their schooling, even widely accepted truths? Was it Einstein who suggested that imagination is more important than knowledge? Putting Einstein aside for one second, I'd much rather people took the time to articulate far more nuanced and individualized opinions on things, rather than accept an "ISM" like feminism lock, stock, and barrel. Idiosyncracies may not make for unity and group cohesion, but it does make for far more rigorous discourse.
