notpashut: “It’s not the label that’s divisive & destructive, it’s the way people use them.”
The labels themselves breed it. It is its very nature.
Another problem with labels is that they “kasher” tarfus. Someone says hey, I’m “left-wing” and my “left-wing gedolim” aren’t makpid about mixed swimming, tznius, etc. So you do yours, and let me do mine.
Btw, when you have a chance ask about this issue to your Rav or someone of his stature and see what they think about it. It may be both surprising and illuminating to you.
