Hard to know if "everyone" hates Ulfric, but I will take your point, he is quite a polarising figure. Obviously if you're a Stormcloak supporter/troop then you'll be a fan of his, if you're not, then there isn't any great reason to like him (that's not to say that you hate him though).

Reasons to dislike/hate Ulfric -

If you are any race other than a Nord the general Stormcloak army are not gonna be your biggest fan, even if Ulfric does not share these opinions, it reflects badly on him, as he is there leader and should encourage discipline rather than just mindless racism.

Argonians aren't allowed inside the city walls.

Dunmer are segregated within the city and it is known that they are treated poorly.

By starting a rebellion he has brought a Civil War to Skyrim, which has/will cost many lives on both sides and still doesn't help the fact that the Thalmor will be waiting regardless of the outcome of the war.

The war unfortunately is exactly what the Thalmor want and they want it to continue for as long as possible, becoming a war of attrition. If it was possible for the difference to be put aside for a few moments, if the Empire and Stormcloaks could work together (as many of the fighter are ex-imperial troops anyway) then perhaps the Thalmor could have been given some trouble and there would have been all round support from the vast majority of Skyrim and the rest of Tamriel.
