I suspect that you weren't privy to the actions and/or comments that resulted in the person being banned. You can pass judgement on a situation without having all the facts but doing so is ill-advised.
It is my understanding that people who break rules receive warnings and should they fail to heed the warnings, they get banned. Bans are seldom capricious or arbitrary. It's also worth remembering that use of these forums is a privilege and not a right. Food for thought.
The right to free speech must be tempered with an understanding that it does not supersede the rights of others. With rights come responsibilities.
