Those rainbow flags indicate to me and my friends that I am welcome and do not need to feel intimidated, and when I see them defaced and destroyed we all feel more unsafe and worry about what is around the corner. It feels like Putin's ideas are making their way over here. And, as you say, it chips away at our sense of worth, enjoyment of and pride in our own sexuality. Straight people are unlikely to experience this same psychological attack when they see the defacement of rainbow flags.
I believe you and I understand why you feel that way.
I am not gay or bi(1). I fully acknowledge the rainbow flag never meant to me what it means to you. Nevertheless it did, and does, mean something to me on an emotional level.
Ten years ago that feeling was positive. Seeing the rainbow flag displayed more and more made me happy and optimistic because it stood for acceptance, tolerance, and opening up of society.
Now it is worry and fear. I feel I must police myself, hide things that are important to me and that I care deeply about, things that I think are ethically important to society, because I cannot trust that the people who fly the flag would treat me fairly if they knew. I cannot trust that they would listen to me and give me a fair hearing rather than assume they already knew everyting they need to know about why people like me feel as we do.
I tell you this not to suggest I have any claim on your flag or that as a straight person my thoughts on the rainbow flag have any relevance, but to explain that my feelings now are not born out of a pre-existing antipathy to the flag and the movement.
So while you may not agree with me and I do not expect you to, can you believe and understand that more and more women, including me, have the same reaction of feeling unsafe and worrying when we see the rainbow and trans flags displayed that you do when you see them defaced? Not because we fear or hate gay and bi people, not because we believe people with trans identies should go back to being what is cultirally expected for their sex, but because we have come to expect hate, misunderstanding, lies and agression against us from the people who now fly that flag?
