Sure the Texas shooting was sad and all, But on the bright side, it's the first time the church got a good sweeping!
I'm not sure what you intend with this statement.  Can you tell me more about it?
Well I just mean, they got a good cleaning
A mass murder at a church is a tragic event for those involved, and for anyone who might have known the victims in any way.  Making jokes like this could really hurt someone, and since you don't know who might be personally connected, it's best not to take that risk.
