Saying "Study?" "Source?" just makes you sound like perhaps you think you're being erudite, or a good debater, when really you're just blowing off anything anyone says to you that comes down against what you think, without commenting on it at all.

Not a good way to make friends and influence people.

And regardless, this is a discussion forum, not a debate club.  Why don't you just say you disagree, and then say what you think, instead of just sounding silly--forgive me--with "Study?" "Source?" all the time? 

You don't accept our conservtive sources anyway and we don't accept your left-wing sources either, so what's the point of all this? 

Let's just converse, eh?  Maybe have a good time disagreeing instead of just annoying the heck out of each other?
