Yes but with free speech comes responsibility. Just because you can doesn't always mean you should. You're free to do what you please. However, consider the fact that everyone knows everyone here and character counts for quite a bit. Maybe consider treating others like you'd like to be treated. Or keep shitting in the sand box. Your call, your reputation.
I don't give two shits if you disagree with me or think I am an asshole. If someone spouts off wildly stupid ideas and does not bother to argue them then I will do what I did. Check out my latest post so you can down vote that as well. Cheers.
So what happens when you spout wildly stupid things that are completely off topic? Should I do something about it? I might consider doing so. I don't need to down-vote a child, their/your attitude will lead to that naturally.
Anger. Free speech platform. Just because you do not like it does not matter in the name of free speech. But then that never matters to hypocrites. Not saying you are.
