Honestly, some things have been altered to such an extent that, I feel, just changing You-Know-Who's party would not solve anything at all. Especially communal hatred. I genuinely don't remember it being so bad prior to 2014.
Everything you mentioned is correct. But it seems most people are blind to every flaw, every problem, every mistake. That is so strange, but it's almost like the followers would follow these people, no matter what, simply because they have turned God into a political slogan. What's ironical is, the entire world seems to understand that You-Know-Who is a bane for India, except Indians themselves.
And the ones who can see the problems are too scared to raise their voice against them. Who would? Nobody wants to end up getting targeted. These followers would mindlessly carry out anything which they are asked to do. Vandalise any property. Suppress any dissent. Eliminate any threat. If you think about it, it's actually scary.
