It's certainly not my main technique, but I am fairly proficient at it. I can kill a twelve bar blues and a vi v i progression too

This is not directed at you, but I think a lot of people criticize slapping because they themselves can not do it well. Yes it is overused by the children in Guitar Center... so what! Kids often do a lot worse things than slap poorly in a crowded music store. Those same kids sound just as bad playing finger style, but no one here is ready to use that as an excuse to give up finger style playing. Hey if a person doesn't want to slap, don't -- I really couldn't care less. But these threads often come off as a defensive rationalization for not gaining some proficiency in a technique that good bass players are expected to have!
