Would be interesting to know in which part of "northeast states most of them are brainwashed with those hinduism parties". I am a north easterner myself and as far as my memory is concerned, hindutva ideology (including their political wing BJP) have never been popular in these part of the countries.
To the OP, the RSS and Hindutva parties have been shouting the same thing over the years, so we can only pray about it. We never know because if Modi comes to power (which is very likely going by the popular polls), anything is possible. During their last governance, BJP (NDA alliance) banned the slaughter of cows. So, we never know what holds for us this time...

Here are a couple of articles I came across on FB (which I feel goes along the line of what the OP fears, now that popular polls have projected BJP Prime Ministerial candidate Modi as the next PM of India
)
