I think this is one of those "context matters" moments, the context here is a BJJ forum where the question why isn't slamming allowed in BJJ Is being answered by multiple people who either havnt trained bjj or have only just started training bjj.
Not explicitly - although it is certainly considered poor form, and some class it as "deliberately trying to injure" which is a DQ.
No. They are not. Folkstyle has a few shadows of the old submissions left in it. But submission is not a means to win in Folkstyle.
http://www.snakepitwigan.com/catch-wrestling-rules/ Snakepit rules are no submissions for the under 18 year olds. Hence catch wrestling without the catch is just called wrestling (Ps wrestling is awesome enough on its own)
The risk to immature growth plates etc is immense, which is why kids bjj comps are so carefully reffed.
It's ironic because you actually have no idea what you're talking about. That video is US Folkstyle, which does have a slamming rule. The Olympic version, which is found much more widely all over the world, is called Freestyle and has no such rule.
There is a limit to what are allowed, but kids do submissions in BJJ and Judo, there is no reason they couldn't in a kids version of catch.
Yeah but even the Folkstyle system allows slams when you go to your knees before your opponent, which is what has been explained already.
Because you were transparently both A) being sarcastic and B) implying that anyone who disagrees with your viewpoint on current BJJ rules must be a white belt
