That hit a nerve then coalition - an example of the tremendous antipathy towards the church. I'm with you on that - though don't have the exact-same points you do - and I am a christian. The church should be deeply ashamed of a lot of its history and rightly so imo. HOwever, the church has not and doesn't necessarily represent christianity or christians. Jesus openly loathed the religious leaders of his day, calling them eg a den of vipers (etc), repeatedly and uncompromisingly condemning them. Imo things haven't changed - 'religion' doesn't represent what should be and is designed to be a relationship, in fact tragically misses the point, the form without the power, "loading up burdens on peoples' backs, not lifting a finger to help". The lovely Jesus said that.
The church aside, the premise of this thread is one christian who has written one book, the subject of which is generally offensive to most - I think that is universally agreed. A debate has ensued about the validity of gays and has sequed into the rights of gays to be parents without feeling they have to justify that. Ok so far. However, I don't accept that the (now accepted and acceptable) bashing and denigrating of christianity and christians should be the result. It is now common in our culture for both christianity and christians to be derided as a matter of course. That is erasing and offensive imo. As a christian, I do take a level of responsibility for the history of the church, and some representatives of the church in the present day, but they/it does not necessarily represent the whole. As everyday muslims flinch from fundamentalist islam, so do many christians similarly flinch from our fundamentalist arm. Don't lump us together.
