You are misconstruing what I am saying. I am saying that you do not have free speech rights on an internet forum. This forum is owned by one single person. All of us post here at his discretion. He can choose arbitrarily what you can and cannot post about.
For example. Let's say that I am part of a gun message board (I am) but someone comes on there and is insistent upon posting about cooking? Well, it is a gun message board if you want to talk about cooking go to a cooking message board. Are your free speech rights being hindered? Not one bit. You can still freely talk about cooking, you just can't do it on that board if the owner so chooses.
The first amendment was written with the federal government in mind. You are free to say what you wish, that doesn't mean others are obliged to give you a forum to do so. That would infringe upon their rights.
I am right. You are wrong
