Healthy boundaries, are needed on social media. As I learned from considerable experience. A lack of boundaries, leaves the door open for unhealthy people.
Healthy boundaries, are also needed on blogs. For the same reasons.
Blogs are not open season for people to be disrespectful. Bloggers should not be expected to keep explaining themselves, or tolerating trolling, no matter how manipulative, or covert the trolling.
I respect other bloggers, and I expect that respect in return.
