For the past few years the rainbow has sadly becomea symbol of silencing, sexual stereotyping and oppression for a lot of women and those in the LGB community. If you're thinking of putting one up, please think about how that may make women feel - many of whom have already experienced death threats and lost their friends and jobs thanks to those who wield the rainbow flag as a weapon.
I just saw two on my walk just now and it made me feel like shit. Not the intended effect I'm sure. Please consider something else: the sun coming out from a cloud, or a simple landscape. Thanks.
