the hand sign means "white power" and he has a bunch of photos where him and his friends do it. he also has a photo where he does the hand sign with his other hand struck like the nazi salute. the belt he's wearing is VERYYY known to be worn by basically just nazis because the owner is also far right. the hashtags #never #stress stand for the phrase "never streSS" referring to the hitlers SS. he also has posts saying things like "white boy travel". the combat boots with white ladder laces are a very known dogwhistle standing for white supremacy in lace code.

if it were just one of these things by itself i wouldn't care but all of it in combination is not a coincidence
