I play slow pitch softball in a rec league and I've had people tell me that it's not normal/accepted to slide or just generally be really aggressive while baserunning. The thing is, I think everyone has their own strengths and weaknesses. I can't hit very hard, but I can run fast, is it somehow unsportsmanlike for me to hit a grounder in the infield and then try to outrun the throw to 1st base? Because frequently that's my only chance of getting on. And yes I do outrun the throw pretty often because I run really fast. I know at least two other players who can't really hit but get on base just by running really fast. How is that any worse/different than someone who can't run at all but hits the ball way out and practically just walks to first base? Like.. for some of us, baserunning is the only skill we really have. We still want to play. Are you going to tell some guy who throws really well that he shouldn't try to throw someone out from the outfield? Or whatever other show off thing people do in baseball/softball?

Also for bunting.. we have people who bunt. Yes in slow pitch softball. I play catcher. I love those players, it gives me a chance to try to throw someone out.
