I'm pretty sure if you weren't an idiot you would know already that as rollerbladers we are unlikely to take offense to retarded comments like that, people with special needs are something you come accept. Even if if we did take offence though, your still an idiot and it has nothing to do with the fact you dislike of rollerblading.
Here are some questions for anyone willing to accept the idea that skiing trick names could be less than perfect, there may be actual answers so don't be too sarcastic.
What is the name given to the basic grind when you come on to a rail from the right hand side and grind right foot forward?
What is it called when when you come on to the rail going backwards so you tails go over first?
What is the difference between switch, fakie and unnatural on a skateboard and is has it been accurately converted into skiings terminology?
Now as far as I know the answers to these questions can be quite confusing, and I know its too late to start now but if we had used blade names from the beginning i think it would be easier to understand.
