Sometimes it's Christians themselves who are singled out; just as often it's the Christian message or Christian religious symbology being suppressed in the public square.
Examples of the Christian message:
(a) I don't see cities rushing to implement a separation of church & state when it comes to other religious expression. For example, the city of San Jose decided to erect a statue to the ancient Aztec god Quetzelcoatl in a downtown park.
(b) I'm not sure if this practice is current, but for the longest of time the New York Times would exclude any books sold under Christian bookseller umbrellas from its bestseller lists.
(c) Public school students have routinely been taken to Native American field trips that include intros to their religious practices...including participating in religious raindances...Scientology books were handed out in some Texas schools in the 90s...the Muslim faith & Koran were studied in CA public school 2 years ago...all examples that if the same thing intro was done by Christians, the left's alarmists would have a cow.
(d) A U.S. West woman in Omaha about a decade ago was barred from the jobsite for wearing her Operation Rescue t-shirt & a pro-life button while at work. Her co-workers would routinely wear t-shirts w/messages, but her message was singled out for exclusion.
Christians themselves: (a) More peaceful Christian pro-lifers were arrested in front of abortion clinics up thru 1994 than were folks in the entire Civil Rights Movement of the 60s. Were they treated disparitely? Yes. While AIDS activists would interrupt services @ Catholic masses in NY...or environmental & peace activists would trespass & interrupt logging efforts (or sit in front of nuclear power plants or missile test site operations)...they would get mere minor fines while the peaceful pro-life activists were often being handed multiple months or even years of jail time...
(b) How often have you seen peaceful protest groups on the left have nunchukus (a martial arts weapon) used on them? Yet hundreds of peaceful pro-life protesters were subjected to this in 1990 in LA & LaMesa, CA...martial arts weapons being twisted & applied to legs & arms resulting in nerve damage & examples where one man had his arm broken above the elbow...it just snapped in two & it sounded like a cannon going off (June 1990, LA).
I can go on, but I s'pose you think Christians having their arms snapped in two is in your words "laughable."
