They unequivocally made my life worse off than without them, and I know I'm not alone.
Us both being willing to accept that our respective experiences are polar opposites, but still valid and worth consideration, is key to making sure neither you nor I are so dedicated to supporting something for the sake of supporting it that we lose sight of why we're supporting it.
Just because it helped you doesn't mean something similar that you're supporting today can't also harm others. Likewise, just because I was harmed by something doesn't mean I should be closed off to the notion that something similar could help others.
If we can keep this in mind when dealing with people of opposing viewpoints, and acknowledge how individual experiences of otherwise similar things can be very different, then I think we'd reach better, less judgmental and vitriolic conclusions on how to solve these problems.
