Currently there are four active humor blogs in the Bloggernacle.
Amazingly, all of them delete material that someone considers personally offensive if you just politely contact them. I try to regularly read them, and used to comment.
Since all entities or groups will draw satire or humor, we can either nurture what we like or reinforce what we don’t by the way we react. Like many things, our choice is not in whether or not humor (like adversity) will exist, merely what shape it will take.
Do some good in the world. Visit some humor sites, encourage the good, pass on the bad. Nurture what you want to see.
