Actually, you clearly don't care about the facts as currently known -- such as witnesses who corroborate the reporter's story. The reporter is "the enemy" to you, and so it's OK for him to be assaulted.
Well, one thing you said is correct. The Left wing Reporter of a Foreign Socialist nation is indeed an "enemy", and so therefore I will not automatically believe whatever he or his allies say about an event with actual political consequences.
I find it perfectly reasonable that we should be suspicious of our political enemies while giving our own allies the benefit of the doubt.
I think it odd that some immediately take up the accusations of their political enemies without trying to see things in the best light for their allies.
I think this tendency to destroy our own is a major part of why Liberals keep advancing and we keep losing ground.
