I don't really understand this position.
Let me spell it out for you, and everyone else.
I support gay marriage. I do not support the methodology of gay couples who wish to be married, filing business ending lawsuits against people who do not agree with the idea of gay marriage based upon their religious beliefs. I think that is overkill and breeds more resentment than acceptance. Just don't support those businesses that do not support gay marriage, the denial of a significant new market for their goods and services will end those businesses soon enough.
Now, to protect the religious freedom to say "no" to a customer without fear of being sued to death, Indiana passed SB 101. This caused Gen Con LLC to put forth an empty threat to leave the state of Indiana. At that point, the corporate owners of Gen Con placed political activism to remove SB 101 before their reason for incorporation - putting on a gaming convention with a very good reputation. A decision I disagree with and do not support. However, one which is supported by SJW activists wholeheartedly, and becomes especially worrisome with the declaration that Gen Con LLC wants to hear about any acts of bigotry against Gen Con attendees (which some will take as an invitation to try and deliberately provoke a reaction).
Now as examples of that SJW activist behavior from the past we have Monte Cook, Zak S, The Pundit, and James Desborogh (GRIMM) being attacked and slandered. We have had people claim that D&D is racist because orcs are a dogwhistle for black people. We have had people claim that Gary Gygax was a misogynist because of the Random Harlot Table. We have had people claim that D&D 5E was anti-feminist because there were not enough female monsters depicted in the Monster Manual.
Lately, in Indiana, we have seen Memories Pizza be decried as homophobic because the owner would not cater a hypothetical gay wedding. A high school coach threatened the business with arson. A group of protestors have taken up at the business and caused them to close down for fear of endangering the employees and staff. The GoFundMe site set up by their lawyer to help cope with the business losses has been declared fraudulent without any evidence by a "concerned reporter" because she disagreed with their stance.
There is plenty of evidence available that these SJW activists are willing to go out of their way to be shitty to those they disagree with.
Now with all that in mind, I do not wish to spend hundreds of dollars at Gen Con to attend the convention. The impression I have is that it will be a hostile social environment because of all this, and I do not want to put up with that when I want to game and especially not when I pay to game.
