No. Correct me if I'm wrong, but Pride isnt about being proud of being LGBTQ, but about being proud of being yourself even if that is difficult. By this logic, straight pride wouldnt make sense. You're not proud of being straight, but you dont have to be yourself in the face of adversity because straight people dont face the troubles LGBTQ people do. I've never seen pride as being proud of your sexuality, more as being proud of the courage it takes to be yourself when people dont approve. Which doesnt affect straight people.
