I don't think all sufis are hated by all orthodox sunnis. Sufis aren't monolithic, some can be as violent/strict in their interpretation as salafis and many have. Saladin was inspired by sufism but was staunchly anti shia and fought the invading crusaders. Another example of violent sufis is someone known as the "mad mullah" (I forgot his real name) he thought he was being overpowered/intoxicated by Allah who was telling him to fight and resist the British in what is now the NWFP, he's an ancestor of mine, apparently
Also the likes of Allama Iqbal who held many unorthodox views are seen as great muslims, he's one of the few men who gets praised by sufis and Al-Qaeda and I think that's down to his anti-secular pro-Islamist and ummah unity views.
As a muslim I hated most sufis, not only because I was taught that they were mushriks who are corrupting Islam but because I didn't like the superstitious stuff, things like bathing in dirty water because some pir/saint used to centuries ago, decorating graves, reading stuff over and over again, the continuous praise of Mo and of course the status given to saints, almost like that of the shia Imams and catholic popes. I preferred me communicating with Allah directly, no middle man and not needing a bearded man telling me what Islam (Quran and hadith) says instead making up my own mind by reading and learning. Being called a "wahhabi" by sufi/barelvis (most british pakis) didn't help change my views.
As a non-muslim I like some aspects of sufism, it tries to explain the relationship between humans and God, which is nice even though I don't think God exists. Some of their views about Jihad, non-muslims, jizya, Islamic state, wife beating and so on are interesting and aren't as dogmatic as those of orthodox sunnis.
But at the end of the day, sufis believe in Allah and Mo-they praise him and try to follow his example (apart from the jihad and politics of course) more than salafis. They don't disagree with shariah law, they only disagree with the Salafi/deobandi/taliban interpretation of it
And recently a lot of prominent sufi clerics in Pakistan have spoken in favour of the blasphemy laws so yeah whatever....
