"Claiming that one is pro-free speech while supporting a company that engages in draconian censorship (not merely "supports their right to", but actually supports and patronizes and defends the companies) is akin to claiming to be against racism whilst patronizing and vocally defending a private golf club that doesn't allow black people to enter. Just because they're not the government doesn't magically make it not racism."
You have a very warped, entitled view of companies' right to censor content they choose. Free speech does, as you say, exist outside of the US Constitution as it's a natural right, not one created by the Bill of Rights, but merely enumerated as one the government had no right to infringe upon. What you don't seem to understand is that neither you nor PDP are being deprived of free speech. You merely cannot say whatever you wish on SOMEONE ELSE'S forum. Everyone has the right to say what they wish, but not the right for those words to be distributed far and wide to an audience through a company that doesn't care to participate in disseminating your message. This is as absurd as if you claimed in the 1800's that book publishers dared to censor your manuscript, or even worse -- not to publish it at all! How DARE THEY step on your free speech by not using their money, clout, and good name to publish your work! And introduce you to their sponsors who will help them pay for distributing it! Do you think everyone in the 1800s had a printing press?!?!? Hardly!
You claim that no one owes anyone anything, but you contradict yourself by implying these companies owe you uncensored speech and go so far as to compare their practices with racism within private clubs as some wrong that you feel they have done to you or others, and therefore you are hurt and damaged by this terrible wrong because they OWE you the right to say what you want on THEIR distribution network.
Youtube isn't yours. They owe you nothing. They owe no one anything. They can censor to their heart's desire, and they do censor quite a lot as it is. You think the nudists aren't irked that their innocent videos of natural human nakedness are deemed immoral and often taken down? You don't get to dictate what freedoms you have with other peoples' things by cloaking yourself in "freedom of speech" when you clearly DO have the freedom to say what you please, but if you don't wish to obey the rules or abide by the whims of your sponsors, you must create your own distribution channel. Start your own newspaper, your own web page, or your own streaming site. PDP has tens of millions of dollars -- He could do it if he wished, and he could do and say whatever he wished so long as it was legal... oh, and he wanted to pay for it himself... or find a sponsor that doesn't mind his peculiar sense of humor.
