Should I join a hockey league (house) right away or practice in public skating sessions first?

If your rink has freestyle sessions, they will ban you from practicing on publics, that's normal. If your rink does not, they still can ban you from practicing on publics. One rink in this country where I used to practice did that, so skaters went to practice on public sessions at other rinks, often travelling an hour for it (in this country, we don't really do freestyle sessions at rinks the way it seems to work in the USA).

At my rink, practicing on publics is ok only if it's not busy and if it causes no dangerous situations. Even then, I have myself had 2 crashes with other skaters over the years, neither was seriously injured luckily (and part of that is that I've resolved myself to taking the brunt of the fall if a collision happens with recreative skaters). Once, I collided with a little kid (which put the fear in me for good frankly) whose mother was absent from the rink (wtf?) who had gotten fascinated by what I was doing (a backward bielman spiral) and got straight in my path right after I'd looked (my toepicks were around my head level pointing up, so essentially he just got knocked over my by standing leg, but I still stopped doing backward spirals after it), and once with an adult skater who was fortunately a good sport about it but I'm sure she must've had nasty bruises to remember it by the next day, after which I realised you can't practice lutzes on publics.

So yes there is some danger to skating on publics. More over, one hockeyer got seriously injured attempting to copy something I was doing and crashing with his jaw on the ice - and while that is his own dumb fault and responsibility, it can for a rink still be reason to not allow such practicing, as it could run up their insurance costs. So book freestyle ice or find a different rink.

This reaction on the side of the rink is completely normal and being allowed to practice on publics is no right, it's a privilege one should be thankful for.

I think what you should do is tell them that if they don't let you practice on in the public skate you are going to leave because you found a much nicer rink. And that if they don't like you doing spins and jumps in public sessions because they don't want you getting in the way of other skaters then that's really rude because in freestyle sessions other skater's get in your way on purpose and they don't care. Make sure you let them know at the other rink there is no bullying so you can freely practice.

So they either let you public skate or do something about the bullying or your going to leave(which means less money).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
