What do you mean by Go and marry .....? You think any boy can go and hold a dalit girl and marry her even against her wishes under the garb of social reformist? If so, you are living in a fool's paradise that is created by the politicians. There are so many inter-caste marriages taking place between the so called upper-lower caste, which obviously you do not seem to be or want to be aware. Are these not the signs of social reforms? Reforms do not happen in a day. It takes time but important thing is to look at it positively. If you are bent upon ignoring the reforms and go on beating around the bush shouting of social discrimination then nobody can help you. You need to break the shackles of your mindset.
