I don't get how LGBTQ colours should be used as the flag of the movement. While solarpunk ideas are inclusive by their very nature, I don't think two ideas being compatiable means they are the same idea....
Cool, I didn't know about some of these, like the connection to the coop movement. However, like all symbols, it has its history and its current use. Since it has been connexted to the queer movement since 1970s I think is fair to expect the vast majority of people to connect it to this movement (and is also fair to the movement as well)
