Yes, I believe it represents who I am now, as do dozens of my friends when we all march behind it at Pride, and when we all remind each other that we have to do what we can to push back against the increasing hostility that is occurring in society now.
We are going backwards to the times people wished we would just disappear, or shut up and sit down. Of course the threads on FWR propagate this as well with the frequent posts about nobody needing to be out, framing it as 'We don't need to hear about your sex life' , when of course it is nothing to do with sex lives, it is just a desire to live openly about who you are in an accepting society.
Covering up our symbol is an attempt to cover up who we are, to make us invisible, to make us ashamed. To push us into a secretive existence out of fear of what encounters we may have.
Some individuals may frame this as a Trans issue - that is not the experience of the hundreds of thousands of gay men and women, who experience hostility to rainbow symbolism as hostility towards themselves.
Mumsnet FWR has perhaps gained ground in this framing exercise, as it attracts people drawn to antipathy towards the rainbow symbolism and rationalises it in this anti-trans context to appeal to others.
But of course Mumsnet FWR is not really very representative of the viewpoints and experiences of gay men and women (I am in social groups which number hundreds of lesbians, and I've not met one yet who isn't aghast when they hear I post on Mumsnet 😂)
