assuming you can still read this: your banning from the forum was nothing to do with your subject matters or voicing your own opinions, but totally to do with your disruptive influence, abusive nature, sarcasm and rudeness, which quite a number of members found to be offensive and I would include myself in that category.
You had been warned about this behavior on 3 separate occasions which you chose to ignore.
I didn't see any alternative.
You are welcome to be reinstated if you can abide by the rules and declare that as such & also avoid the above reasons for your banishment.
