>>803360Smarta sect upholds caste system as far as I know, as in, you can't convert to it unless you're born into it. Popular sects like Shaivism, shaktism, Vaishnavism, etc of which the vast majority of Hindus belong don't really stress the caste and are therefore more open to foreigners, take the Hare Krishna's for instance, they say that true caste is based on meritocracy (virtue)!and peoples inborn nature, for instance a person who is into politics and and justice on the temporal plane of existence has a 'warrior' nature and therefore would assume a function in executing law in society whereas someone who is more intellectual and introverted would take their place inevitably among the priest caste, etc.
