It's sad and upsetting.
There's actually an article of a KKK Grandmaster who speaks against WBC. Picture it: The Head Racist saying the WBC is wrong. Interesting in itself.

The issues surrounding WBC are many and interesting to study all in itself. As a church (and being citizens) they are allowed to exercise free speech. However, you can see some bias of allowing some groups (like WBC) to protest over others, such as women's rights protestors. They are met with much less police resistance than other peaceful protests. The social issues behind it are very intriguing to me.
Also, the church is open because they are able to indoctrinate their children into the hate, thus having members and control. They're also a whole bunch of lawyers, which doesn't hurt.
However, to go back to your comment, it depends on what Christianity you mean. If we go back to the dark age and fiefdoms, Christianity was not very moralistic. It was used by the Barons and Dukes to control the peasants. Such quotes like the camel and needle were used for this.
There are many forms and breakdowns, etc. I wish that the norm were loving, open Christians. In my personal experience, these loving Christians seem to be an ideal and rarity. I've had a friend excommunicated from their church and family because they were gay. I do not think they held the ideas of Jesus. I have other stories, but I don't wish to flood this comment.
I'm all for Jesus's philosophy and I think I use most of these morals. I have spiritual and religious friends who are open, committed to their faith, and loving. I wish everyone was like that.
Sorry to write a book. I studied some of these things in school, so they are of high interest.
