I get the sentiment but I must stress the fact that russia shoots at anyone they see first. Doesn't matter who you are, you can be a civilian covered in white flags or visibly an old person/child, they shoot everyone. It's not like they pick and choose their targets at the frontline, they just shoot.
And if you're worrying about people being tortured for being queer if they get captured by russia, then you must know that they torture everyone. Civilians, warriors of all genders, anyone who gets captured. There have been reports of rape and castration as part of torture by russians no matter the gender or age of the captured person.
They don't even care about the affiliation of the captured person. Recently one woman from occupied areas ran away to Ukrainian troops for help because russians came to her home, killed her husband and raped her. Turned out she stayed in the occupied area to wait for "the russian liberators" until she found out what they really were like.
So the patches aren't the danger, russians having no repercussions for killing and torturing people is. And they already hate us all, a patch isn't going to change their opinion.
