While it is a very good idea to have factional mutant acceptance, it seems best to include a case-by-case variance. For instance, one person may be partial or even infatuated to certaint kinda of mutants, but outwardly hide it around their comrades due to social stigma of the faction.
Just as well, it seems that sufficient speech slill and intelligence should be able to override the negative social effects of having the “psycopathy” styled mutations. Who says my character is not allowed to like people?
