How to pretend your free speech is being infringed upon when it is not:
Step 1. Say some outright bigotry bullshit under the cover of your constitutionally protected right to do so. It doesn't even matter if you use a bunch of supremacy symbols that people are "wink wink/nudge nudge" about. Be sure to be privileged and say it about groups that are already marginalized. (Otherwise this could backfire.) But if you do it right, folks–even on the left–will insist on the need to hear you out and provide you with microphones and podiums and sites for your hate speech as part of their deep value of free expression.
Step 2. Once you are known for exactly the sort of message you will deliver every time you open your mouth, schedule a venue in a super liberal area. You might even consider nudging that hate speech needle over toward inciting violence JUUUUUST a little. I mean you still want plausible deniability of course. Bring a gang that likes to provoke people (but of course you can't possibly control them DIRECTLY). Don't worry, this won't be held against you in the final analysis. Hopefully you can provoke someone into taking a punch. No nuance will be examined about high running emotions or the level of provocation you and your people used. No matter what happens (including often if your folks throw the first punch and your opposition had the temerity to fight back), people will think you just came there to talk and be reasonable and the evil leftists showed up just spoiling for an anti-first amendment fight.
Step 3. Some progressive protestors will then exercise their OWN freedom of expression to protest your event. Don't worry that their speech is as free as yours–you have this wired. You live in a land where the perception is that anger isn't free speech, but urbanely espousing bigotry is. They may do so by trying to appeal to the venue or arrange a concurrent event. At this point, you've already won, no matter what happens.
Step 4. The venue will then decide whether it is worth it and/or if they have the security necessary to host your event. If you are lucky, you will lose your venue, but the beauty of this is that it will work even if you are allowed to speak but someone dares criticize you. You're already in the clear.=
Step 5. At NO time will the government send agents to intervene in your free expression. No one will arrest you for speaking. Your published materials will not be seized by agents of the state and destroyed. If there is a policing presence at all, they will let you say anything you want short of outright imminent threats, and may not even intervene then. This doesn't matter.
Step 6. If you had your venue cancelled, or even if you didn't, you can whinge about how unfair the left is and how they stood in the way of your free speech with their overbearing opinions, and so much for their vaunted values of tolerance and free expression. Even their own people will wonder if they're "hurting their own cause."
Milk it like you're a men's soccer player who actually got kicked.
