Thought for the day

If I started using the term "anti-Semitic" as a general term of undifferentiated disapprobation like "lame" or "gay" (as in "god, those trainers are pretty anti-Semitic", "The first few series of Friends were quite sharp and funny, but it got really lazy and anti-Semitic toward the end", "I don't know; there's nothing specific about Shoreditch that I don't like - it's just a bit anti-Semitic"), how long do you think it would take to catch on? And what sort of reaction would I get in the meantime?
