Tolerance has never been the goal. As Mark Shea now and then says, LGBSA and like organizations do not want tolerance. What they want is praise - and they want anyone who would ever criticize their acts to be bullied, shamed, shunned, fired from their jobs, or worse. This video shows some of this in action - along with the great hypocrisy of an anti-bullying speaker bullying others and encouraging them to do the same. Naturally, everyone who disagrees with him is automatically considered a bully in his mind.
And this just helps to highlight why "dialogue" is something I don't regard as valuable. People always forget that what makes dialogue possible is shared values - and even then, there has to be enough shared values present to foster mutual respect and understanding. With many people, particularly nowadays, dialogue is not possible. There's not enough common ground.
That doesn't mean conversation or debate isn't possible. It just means that there's no actual dialogue or interaction had, or even desired.
