No. All of the queer people I know hate the ally flag. Why? Because the point of being an ally is that you're supposed to be supporting the community as one of us. By flying the ally flag, you're setting yourself apart and distancing yourself from queer people. You're essentially saying, "I'm not actually gay, I just support gays". If you wanna actually be an ally, fly a rainbow flag and let them confuse you for being gay. That's where you're actually putting yourself at risk, and that's where true allyship exists. Otherwise you could be a coward and walk away whenever the heat gets too intense.
