How caste Brahmins made blatant distortion to the meaning of this verse from GITA?

Time has changed.Even present Government is doing every thing based on caste.Can you change it?The four varnas should not be taken as caste differentiation at the time of it s initiation as it was based purely on distribution of work.Whoever was having intellectual talent were termed as brahmans.Let us take good from Gita &follow it.Do not be oversensitive on this issue.
