Okay, so keeping in mind that I'm really not up on the whole "Berkeley protest" thing, and I have no idea whether I would support it or not...
I just want to say, as a present day Unitarian who was raised Quaker, being "tolerant" does not mean tolerating anything and everything. Most especially, as a person of good conscience, it means you MUST stand up and speak out against intolerance, and bigotry, wherever you see it.
As a child, for example, it was made very clear to me that if I heard someone use the "n-word", I was NOT, under any circumstances, to tolerate it. Silence is as bad as agreement. I had a responsibility, as a Quaker child, to speak up clear and state that I would not tolerate that kind of language or attitude toward my fellow human beings. My tolerance ends where your intolerance begins.
This can, indeed, lead to conflict. It can lead to shouting and placard-waving, and catastrophic failures in communication. On the other hand, as my pastor was saying just last Sunday, conflict, while uncomfortable and sometimes distressing, is still necessary for growth.
So, I remain hopeful.
