listen to me!
The all-pink lesbian flag (left) was created by a racist and biphobe (+ probably more problematic stuff) in 2010.
The orange and pink lesbian flag was made in 2018 as a non-problematic alternative.
Something I wanted to point out is that the all pink flag was +

created in 2010, while the orange and pink one was in 2018. Before 2018 most people didn't know the flag on the left was problematic. That's why in the majority of pride posts made before 2018 this flag was used. If you see that flag, it's likely that the post was made before +

2018. It doesn't excuse that the flag is problematic, however back then most people didn't know it was bad and there wasn't another well known alternative. This flag is still problematic, but you shouldn't assume that people who used it before 2018 are problematic. The all pink +

one was the most well known lesbian flag a while back. While it doesn't excuse what the creator has done, you shouldn't shame people's posts made before 2018 for using that flag because the orange and pink lesbian flag wasn't created yet. Now, though you should definitely use +

the orange and pink one since it's the most widely known now. End of thread! If you have any questions please don't hesitate to ask.
