Do people have the moral 'right' to call each other fat?

1 - Depends on how fat. True. But all fatness is unhealthy to an extent
2 - Untrue. Someone can be fat simply because they particularly enjoy their food, not due to any self-respect issues. I'm overweight but I can assure you I have absolutely no self-respect issues.
I maintain that this is true. You may not have any self esteem issue, which is great but the fact that you are happily overweight show a lack of self respect to me.
3 - That's a personal opinion and you're entitled to it. However, not everyone has that opinion, and again it depends on how fat.
True but I can guarantee that the majority of people share this view.
4 - Could you explain this? I don't see how someone being fat makes them inconsiderate... It's inconsiderate because the extra weight causes vehicles to use more fuel, other people to have less space on aeroplanes, trains etc and fat related health problems cost the NHS rather a lot of money.

The same thing could be said about Hitler or Stalin but many people (on here as well) give them a lot of abuse

Interesting question. I think if it isn't relevant to the conservation, then it's likely to be perceived as rude or offensive.

I believe in freedom of speech, even for people who's views I strongly oppose, but gratuitous 'fat' comments could end up as verbal abuse, bullying, or worse. I've never understood why using 'ginger' as an insult is hardly ever challenged either.

Likening fat people to bloodthirsty dictators..well done.

really?

patronising me because I am right, doesn't strengthen your argument, it weakens it.
And I would regard them as "bloodthirsty"

It depends how you define healthy.

I'm not patronising you, I'm pointing out the stupidity of what you just said.

There was no stupidity in what I said. I wouldn't expect someone so obsessed with Game of Thrones to understand.....

Not all of them are capable. By pointing out their flaws, you make them insecure about themselves (as they should be) and more determined to change.

And FYI I don't just see a fat person on the street, point and call them fat. And I don't not like people because they are fat.

BUT if anyone ever asks me about their weight, or says something to suggest they think they aren't fat when they are, I correct them.

Unhealthy is the only one I agree with, and learn to ****ing spell it correct next time you shallow dip****

That's a massive assumption.

In what definition is being overweight healthy?

Need I define an ad-hominem?

Something that has increasingly been bothering me is when people need to comment on each others weight. For example, "are you watching your weight?", "don't eat chocolate, think of the calories", or even more offensively... "you would be more attractive if it wasn't for the size". (Just because someone is big it doesn't mean they're automatically going to be ugly).

The only concerns which I think are valid: 1) you're going out with the person, 2) you're funding their eating or food, or 3) genuine health concern.

Other than that, KEEP YOUR NOSE OUT OF OTHER PEOPLE'S BUSINESS.

EDIT: I don't oppose their freedom of speech to say it, but I don't think they should expect others to accept it or change to suit them.

Are you sure?

No you do not... I do enough Latin to understand what you are talking about....
But the concept is stupid

In what definition is being overweight healthy?

Yes they do.

We have every right to be inquisitive, opinionated and rude if we want to.
