It would be nice if there was more acceptance and toleration. I often have to delete such comments and continue forward. I do not try to engage them when it is apparent that they are wanting to vent rather than rationally address some concern. This is part of the price tag of free speech. Some people will use it to be abusive.
It is sad that people stoop to such levels. In my case, most of those who are abusive toward my hubs are not members of the hub community. Mainly outsiders who just stop in, drop off their bombs and move on.
I wish you the best in dealing with those pesky comments.
