friend, two points you ought to understand.
One, posting on YouTube or Facebook or Christianchat.com is not a constitutionally guaranteed right. I hat is not how 'freedom of speech' is defined. Beside the fact that those are all privately owned and operated organizations that have the freedom to do whatever they like, there are cases where you don't have freedom of speech. You can't incite violence, sedition or treason and hide behind the 1st amendment, for example.
Two, the way the law works in this nation is 'innocent until proven guilty' not the other way around. This is also a basic tenet of logical argumentation; the burden of proof lies with the person making the extraordinary claims.
Be a Christian, not a republican or a democrat. Be wise, not a fool driven about by every wind of conspiracy and cult of personality.
