“How come I have to prove everything I say, but you never have to back up your claims.”
You made a claim that I (and probably no one else here) are familiar with when you said “Obama told Putin he could have Ukraine when he was president”. Are we supposed to take you at your word here? You wouldn’t let me do the same.
But it's a textbook Alinksy tactic - make the other party prove their assertions, but never do it yourself.
May I ask what country you live in?
