Which vedas you have read about caste. I do not think any vedas talk about caste system. They talk about varnas. Castes was later formed because of the ways people got married and the way manu decided thier work.
The varna system was based upon human inteligence and not the caste system. The caste system is purely based upon birth.
If you are such a believer of caste system, why brahmins are becoming engineers, doctors, businessmen?
Brahmins have always used vedas for their own benifits. Today you call Hindu a "sanatan dharma". But is it really a sanatan dhrama? why did you stop worshiping sun, agni, indra as described in vedas and started worshipping "Shiva" and "vishnu" which are not vedic gods but tantrik gods.
The only thing I can say about all you guys is you are nothing but hipocrite.
