Indian siciety is alredy divide into castes for genarations. Today also 70% population remains in villages where caste system is deep rooted and higher cast is taking advantage of that. low caste people are still not allowed ytake water from main source in village and upper caste is having access to all facilities like education water and local political power whtether they are rich or poor.
So I donot see any harm if lower caste are allowed to come up by reseravation.Balace vacancies in employment and education we should compete what is wrong in that. Creat more opportunities in job and more seats in education institutes so as to compensate open category candidates.
Those who are thinking to upbring lower castes are not mentally sick but they are generatios forward.. Here i do not consider opportunistic politicians who want to take advantage of caste politics or who want raise hindu religeous or muslim religeous sentiments . They are threat to nation.
