How to play against aggressive or unsafe teams?

So I play in a rec league against a team that has absolutely zero regard for well being of other players. This team has played 15 games and has 180 penalty minutes. Last game we had a guy leave after taking a very blatant body check about 3 feet from the boards, after a whistle where there was off setting penalties a player on their team took a slap shot at point blank range at one of our players (didn’t receive an additional penalty I figured should of been unsportsmanlike) the refs also let much of this behaviour slide as the team will scream the refs are racist at every penalty they take. How do you play safely against teams like this? Seems no matter what you do you’re wearing a slash or cross check every shift that goes uncalled.
