I am sorry, but this is like complaining that the free food at the shelter doesn't cater to your desires despite the fact that it is the biggest shelter in town.
I understand that folks are upset. I am too. There are risks with relying on the proverbial kindness of strangers and one of them is that the strangers may discontinue that kindness, which is what we see happening here. YouTube isn't squashing our free speech anymore that Todd is by censoring things here on LSB or moderators do on countless forums. They are all privately owned entities where the owners and their staff get to make the rules. The 1st Amendment doesn't apply. They have the right to control the content on their websites and you can be darned sure that they don't want to give up that right, either.
We should have all prepared better, but we didn't.
However, if you or anyone else feels this is a viable 1st Amendment issue, file suit. Contact the NRA (which as been very quiet on this issue, no doubt because their lawyers understand the futility of such an endeavor) and the ACLU.
