Honestly, I don't judge till I know the person. I know two people personally that grew up in poverty and turned to a life of crime. Received prison sentences up in the years. Came out tagged. They said they didn't want to, they regret it, but genuinely felt they had no other choice. They both had similar stories of needing to join a group, and the other races wouldn't have them.
They both say they don't hate any other race, and from years of interaction, work, I believe them.
You just don't know a person's circumstance some times. On some level I feel kind of bad for them.
That said I'm not itching to make new friends who carry that symbology.
But to put it in persoective, I also know of someone with a similar story (poverty, crime, prison) and he's a full blown racist on another level who should be in prison right now.
