Going solely on the facts:
1. 2014- 2015: Member was asked repeatedly to cease comments which was determined by the moderating team to primarily to antagonize members here and elicit a response
2. 2016: Member was given a 2 week suspension for ignoring Moderator requests to cease said antagonistic comments.
3. 2017:Member continued to post same antagonistic comments after multiple warnings and a previous 2-week suspension, thus gaining a 6 month suspension.
Going on this and this alone, I see this as defiance of Moderator requests and worthy of the suspension. In fact, going by the pattern, he should be banned same time next year, unless he makes a behavioral change.
In all honesty, I really don't see why this is such an issue. Facts are facts: He chose to ignore the moderating team's requests repeatedly.
Going by the information at hand, I'd say he has been given more than enough chances and when he defies the request again, I for one will be voting for banishment.
