SeiserL: Thanks. Tried the first two and it didn't work. Reporting it to sensei isn't going to work unless he's going to intervene, which I'm told, he won't. But thanks.
That does not speak well of Sensei. Its is their job to keep the mats safe for everyone.
Have any of you Sempai seen it? Would they be willing to intervene? I often take a very protective stance.
If you have said it all with words, and want to continue to train there, expect that he will stay who he is and will make advances. Don't take it personally. SIlently and proudly just walk away and train with someone you can trust.
