Otherwise you will be subverted and undermined at every opportunity and I’d rather live in authoritarian Christian state than what the Left will bring any time.
The Left would bring freedom, opportunity and self-determination for everyone with laws only restricting stuff that hurts others, like murder, theft or rape. Just because you want your life decided for you and micromanaged doesn't mean everyone else does. You can personally follow your narrow Judeo-Christian Shariah anytime as much as you want....no one's stopping you.
Also; Hasn't it ever occurred to you that, if you didn't present the Christian Faith as this hateful, close-minded fascist mess that hates everything and is the ultimate killjoy, stuff like "Piss Christ" wouldn't be MADE?
If you focused on condemning only stuff that truly hurts people, focused on love, kindness and charity and presented "The God of Love" rather than "The God of Wrath" then Christianity would grow by leaps and bounds as the great, holistic, progressive, humanitarian, soul-healing Way of Peace and Salvation it was meant to be.
Andrea Cerrano had been burned by bogus "Christians" and corrupt churches enough. Granted; It's a bit rash to put Jesus himself (or a cheesy plastic crucifix depicting him) in a jar of urine (when Jesus himself was mostly pretty cool) but the point's still made....Religious Frummery, authoritarianism, killjoyism, bigotry, hatred and hypocrisy will alienate potential believers. Better to spread a faith by stressing Deity's love and yearning to heal, aid, provide guidance & meaning, etc.
Making an old adage more accurate, I say; You can attract more bees with honey than with ammonia.
