That is a noble ideal. I support it completely. Alas, the reality is that some feel compelled to force their beliefs on others. For purposes of illustration, let's confine the discussion to our lot, the transgendered. I'll use just one case, one familiar to many here, as an example. How is the treatment received by Kai Shappley in any way, "peaceful" or "agreeable"? How is it "intolerant" to call those who perpetrate such injustice ignorant and intolerant?
Caution: Before you reply with an indignant assertion that "It's not ignorance. It's their deeply held beliefs", know that I am not questioning their beliefs. They can believe anything they want. It's their actions, and in many cases, inaction, that I refuse to "tolerate".
Now, again, tell me how it is that we should all just "disagree agreeably"?
