I mean that this current infraction seems fair, and quoted a recent post of yours to demonstrate that you have made similarly offensive comments recently.
You feel that addicts are weak and you are entitled to your opinion, but as per the site rules, you may not go around stating that opinion where it is inappropriate and/or disruptive for you to do so. For example, I am of the opinion that some people are total douchebags, but I do not go around posting that opinion in serious discussion threads.
This is all very straightforward. If you are still unable to comprehend these simple rules, then I very much doubt that anything more can be done to help you understand.
