Consider that people vary greatly, particularly skins. Having been one all my life I have known some that fit the description you give and some much less appealing. I also know many who are nothing at all like that. I am sure that you, like any racialist, are misjudged by many. Indeed the average person would likely have just as negative a preconception of you as you have of all skinheads. I find it easier to explain in the average.
Some skinheads are no account drunks, some distain consuming any intoxicants. Some skinheads racist (like myself), some are nonracist, some are antiracist. By all the gods some are not even White (though I've never encountered such a one in the US, they do exist and have since the beginning)!
Whatever reasons you may have for not liking individuals from your past, the fact that they were skinheads is incidental. It is unfortunate that those were the skinheads that you knew. I can assure you with complete confidence that not all skinheads are like that.
