And if it were me personally, I would contact the ACLU. I know there are competing opinions for the organization, but a book club run by a government organization is held to standards no matter how small or how close knit the town is. This sounds like something the ACLU would take interest in, even if it only involved sending some letters. My friend was suspended from a Louisiana public elementary school for 2 weeks during the 90's for refusing to take a free Bible from the Gideons people when they went to her school and handed them out during class.
She said "No thanks" and they suspended her. Her Dad contacted the ACLU and filed a lawsuit against the school.
Whoever put that list together should lose their job in a very public manner and it should be well known why. How in the great blue hell someone can go to a public library and organize an anti-Mormon book club (I know I'm reaching with this claim, but whatever. It holds and I'm mad about it) like this baffles and infuriates me.
There is no other group, religious, social or otherwise, that is more publicly acceptable to bash and flat out discriminate against than Latter-day Saints and the church. Persecution is part of the deal, and is a quality of the true church. I get that. I accept that. Mostly. Not so much at this exact moment, but I do get it. Still, I wouldn't lay down for this, and I wouldn't show "tolerance" for it either. And anyone who does is more worthy to be on some "blacklist" or fired from their job than anyone who made a donation to a federally sanctioned voting campaign.
Fun story about me and how I overreact in situations like this, please feel free to ignore ...
I'm a disabled Iraqi war vet and I've played that card and written my state senators before when I've felt I'd been wronged by a company or by a govt organization. Like when Bank of America thought they were entitled to $171.00 of my money in bogus late charges. I sent all my paperwork to the comptroller of currency for the United States of America along with a note letting them know that Bank of America steals money from disabled veterans. I made sure I wrote that on their complaint form so it would be official. It's a long story, but I had several bank employees who backed up my claim that BoA took money out of my account that they were not entitled to and called it "fees" and no one was able to give it back. Within a week I received a call from the office of the CEO, some public relations weasel, who said he was contacted by the department of treasury about my complaint and as a courtesy was refunding my money. I argued with him for about 20 minutes. He never claimed that BoA was wrong and in fact told me I should be grateful that BoA is as generous as they are in refunding my money. My final answer on the subject to him was that BoA had a proven track record of behaving exactly the opposite of how they were now and that if they were as generous as he was claiming, they wouldn't be in business anymore. I also told him the only reason I was getting my money was because the department of treasury reviewed my case and told BoA to pay me, because I was right. This was before I converted to the church and I used much more colorful language than I'm recounting here. I told him he and his company were vampires. Vampires who had made their fortunes by raping poor people out of money they don't have and no matter what he called it or how he dressed it up, Bank of America was giving me my money back because I was right and there was nothing he could do about it.
It's 5am I've yet to go to bed yet and this is why posting while exhausted is never a good choice.
