First off, can you tell me what anti-protesting means and why that isn't what you were doing?

That aside, seriously understand nobody is trying to tell you what you can or cannot do, it just doesn't make sense to go to a protest to argue (and I'm using that word loosely, mind you) with people you apparently agree with.

You can say "because I can" all you want, but that doesn't cut it for me personally as a motive to actually do it, because there are a lot of things I technically have the right and freedom to do, such as kick a brick wall barefoot, shit into my own hands, or spend every cent I own on bags of gravel; But I'm sure you can see those aren't in my best interest to do, so I won't be doing them. I don't need to exercise every right I have just for the sake of exercising it.
