I don't know how a person in a matter of weeks can go from at the very least accepting (if not advocating) of the idea of genocide as an "answer" to that "question" could do a complete 180. When people are that deranged they are very willing to publicly recant views that they realize are not publicly acceptable while still believing it in private.
Yeah especially when the comments include talk about 'hiding your power level' which is explicitly about lying about your views to blend in and stealthily introduce fash/antisemetic/alt-right talking points to people without immediately turning them away or getting banned.
the first thing he said in that imgur link was that he thinks its okay to "hide your power level" . he is clearly okay with and willing to hide his real beliefs
Yeah, no. A well-written one, but clearly not an honest one. You probably don't go from a literal (not the way the term is often thrown around, but literal) comprehensive neo-Nazi belief system to suddenly thinking neo-Nazi beliefs are bad in the span of a few weeks. From thinking Jews run the world and need to all be killed to "oops, nevermind". He's just sorry he got exposed.
