No, not at all. Hinduism is a slave-system where slaves have a duty towards their caste, vocation is an expression of positive freedom, of your own recognition that you have been born to do something.
Hinduism is a religion and way of life, first of all.
Secondly if you're actually making an honest mistake and not being completely ignorant, you probably meant that the caste system is a slave-system. And I can agree, it's been horrible, and it has no scriptural authority in Hinduism. Svadharma is not the caste system and the caste system is not Hindu.
> vocation is an expression of positive freedom, of your own recognition that you have been born to do something.
There is no need to act offended, if I am mistaken so is every encyclopedia on the web. Svadharma is defined as duty towards your place in the caste system, I'm pretty sure castes play an important role in the Vedas but I has been a while.
If this isn't the case my bad, but please provide resources because every resource online seems to be wrong.
