Arrogant pro-LGBT Christians

These may be some of the most obnoxious Christians one can encounter. They actually hold OK views in regards to humanity, but it seems like they want to credit Christianity for it. They'll go about calling themselves "true Christians." It is so terribly arrogant. Just think about some of the implications:

• Most Christians throughout history have not been "true Christians." And it is in only recent history -- we're talking only 20 years here -- that the percentage of "true Christians" has risen, and risen quickly.
• No Pope has ever been a "true Christian." Not even the current one that people like to believe is progressive.
  

Sorry, but I find it really hard to believe that after nearly 2000 years Christians would only just now be reaching a tipping point of the majority discovering the "true" message of Jesus. Not buying it. As far as I can tell, the change in attitude is all thanks to the LGBT community refusing to put up with discrimination. Christianity played no part in this. Yet, these Christians act like it somehow did. It's frustrating because it's been Christianity that has provided the most resistance to change and it will likely be Christianity (and other religions) that provide the most resistance to changing future injustices. These liberal Christians are doing the world no favors by trying to keep their mythology alive.
