His weight has nothing to do with his political views, he's just a vile person who happens to also be fat.
Republicans are free to refer to Obama as a half breed if that's what they want to do. Only a total fool would think that being multiracial is something bad. Same thing with attacking someone for being female. Additionally, being overweight is not the same as being crippled by polio.
You don't understand it. When attacking people for these things is 'ok', it fosters a cultural bigotry that is harmful. How long was it ok to treat, say, blacks as 'inferior' in our society, to deny them opportunities, to lynch them as good family entertainment a town could bring the kids to watch, to use the N word as a constant reminder they were second class, to segregate the country for a century from drinking fountains to restaurants to nightclubs where blacks could entertain but not enter as guests? Where did that mentality come from?
Your defense of 'it's no problem' leads to those bigotries being stronger - you might remember women couldn't vote for over half of American history. That's the 'gender attack' in action when it's accepted by society. The only reason it's not rewarding to exploit attacks on women now is because of a century of people fighting against that bigotry. NOW they're 'equal', at least in many ways. You would roll those gains back. Not your intent to do so, but the effect of your condeming the stands against bigotry.
Should we slide back on things like respect for people without bigotry for race - so that Rick Perry's '******head' ranch is not a problem, maybe a bit funny, instead of a negative for him showing a background of tolerance for racism? When Ann Coulter isn't criticized for 'lovely human', bigotry harming equality such as gay marriage, gay adoption, military increases.
It's unthinkable that the progress for gay equality could have happened for most of American history - you would protect the bigotry to return in the name of free speech.
Let's be clear - I'm not saying to shoot people who say offensive things. I'm basically for the 'free speech' and 'market' of speech too.
But that's what I'm demanding - that the market be a market and condemn the bad speech, while people like Maher - and you here - are demanding the market be quiet.
As for the place of insults about weight, epsecially about political figures - they have the same relvance as race or physical disability. They're irrelevant and wrong to people.
Maybe you want to defend Limbaugh's attacks on Michael J. Fox while you're defending your own attacks on Liimbaugh's weight. Your comments are no better.
