Well, LGBT fought for equality - now they have equality. In fact, minorities now have more right than majorities, e.g., recent Oscars rules specified the minimum percentage of minority actors in film, but not the maximum percentage, which, given that all percentages add up to 100%, means that the majorities now have upper limits on representation but not a low limit. My point: if you want equality - you can have it. But do not try to be "more equal then everybody else". If it is OK to promote LGBT on public roads, it should be equally OK to say "God is against abortions" or "Marriage is a union of men and women".
There is a relevant joke about it: Why it is OK for a vegetarian who comes to a non-vegetarian party to bring his own vegetarian meal but not OK for a meat eater who comes to vegetarian party to bring his own cheeseburger? Or a more general question: why meat-eaters are expected to accommodate vegetarian quests while vegetarian hosts rarely prepare meats for his guests?
