Flame, with due respect, I think you missed the point and have now made an attempt to move the conversation into a broader area. The writer was merely pointing out to his gay brethren that in light of the struggles they have encountered with hateful speech, that they might be more sensitive toward the feelings of TG. No where did I see him attempting to pit one against the other at all, but rather to bring them together.
Nor, do I believe the article came close to entering the ugly waters of divisive politics which you suggest, and seem to wish to further with your remarks. This was not about political correctness, or any other cynical catchphrase soundbite, but simply one person pointing out to his readers that their unthinking remarks are likely to cause unnecessary pain to others with whom they have something in common. Is it really necessary to broaden that into a foray into personal political belief?
