That sucks and I am sorry to hear about your bullying issue, but never feel shy or scared of expressing your opinion especially when it comes to things that you enjoy or hold dear.
Don't feel like you can only give your opinion if others feel the same, it's a forum and different opinions happen all the time and can make for a decent discussion, remember at the end of the day we are all devils fans here!
We had the same rule at my school and to be honest I wasn't very good at obeying that rule but I envy you for doing that and wish I made more of an effort.
But back on topic, being welsh and proud like we all are it was very disrespectful what Walser did.
He is a good player/coach but all respect has been lost regardless of the ' apology ' he gave.
