Why do so many people think it's okay to use weight discrimination against Rob Ford because they dislike his politics and decisions? I have some big problems with this.
1. If you make fun of the weight of a fat person you don't like, you are making fun of the weight of everyone who is heavy.
Using weight as an insult, an often ignorant and cruel insult, shows that you discriminate against all heavy people, especially when you assume things about the person's character, based on his weight. Many people only reveal their problem with heavy people, or at least only become conscious of it, when the subjects are people they don't like.
2. Schoolyard bullying tactics are not effective or logical discourse.
What does Rob Ford's weight have to do with his policies? What does making fun of his weight accomplish? The only explanation I can think of is that they think his weight is a reflection of his character, evidence of his supposed incompetence, lack of interest in issues and a reason he is so disliked. The stigma against heavy people. If you use weight to assassinate someone's character, you're just a bully. An ignorant bully. And you're contributing nothing, except to the stigma against heavy people.
3. You can't justify making fun of someone's weight.
Liberal opponents of Ford, who would normally be against making fun of people's weight, start using weight as a weapon against Ford. I've read arguments for this like "Well, he's done our city wrong, so calling him fat is okay." Why is it a privilege to avoid discrimination? This implies that it's something that must be earned. You might as well say, "I'll only call you a fatty if you do something I don't like," or "I'll only let myself stigmatize fat people if I don't like them," Such a deal doesn't even make sense. The purpose of discrimination is to bring down the entire group with the undesired feature, not, as many argue, to just make fun of the individuals they cherry pick to support their agenda.
