sticky situation. I understand both sides of the argument. If it were me, I think I would just steer clear. Like I don't feel such a strong desire to emulate Pat that I would do something that i know would be perceived as offensive or problematic by a non insubstantial amount of the population. If it really did matter that much to me to dress up as Pat, then I guess i would just wear a helmet.
Otherwise, pick a different player to dress up as. you'll be fine, its just a costume.
