I think he's a kook by taking Halloween that serious and posting his costume on social media. At least for me, skaters back in the day didn't care much for dressing up on Halloween...If they did, the costume was definitely evident they skated or don't give a fuck...They didn't really care about anything other than skating, mags, and vids...way more militant than today's standard.
It's still weird for me to see skaters in 2019 culturally behaving like people who don't skate. Even though most skaters having been acting like regular people for at least 15 years. Add that to the major ignorance of his costume, and he's a huge kook. I dont think he needs any attention either positive, negative, apology, group hugs, etc...just let him fade into obscurity.
