The problem with this approach is you have no idea what will become wrongthink in the future. In 2008, opposing gay marriage was a relatively mainstream idea. In 2014 someone was fired for donating to an anti-gay marriage campaign. In 2015 it might be acceptable for one to express wariness of expanding the H-1B visa program, but in 2020 will it be so?

See how they've even turned against Banksy for his so-called "anti-immigrant" piece, which was meant to satirize anti-immigration ideas.
