Communalism is first step. Then minds become criminal and that is the most worrying aspect for any society.
If X commits theft in your house, will you go to his house & commit theft?
For example, if a woman is molested, accused must be booked, not that a woman of other side be molested in revenge.
Mob mentality leads to rise in dirty thought process and casual hateful remarks become common.
Media groups want eyeballs and hence headlines are given with the aim to draw attention.
Thousands of crimes daily but one is taken up. Clear sides are taken and people become so brainwashed that they refuse to see reason.
Entire groups are seen as enemies and then all energies are directed at them.
This level of hateful behaviour makes people blind and they keep getting radicalized.
Most often it's not in the interest of the people but in the moment, whipped up sentiments, passion and anger appeal more.
Sometimes, ten or twenty years from now, a few people among them who have spend their lives drowned in hate, realize that it was the time they wasted.
Many others still won't as people like to justify their acts as accepting own fault is rare.
If you want a better future for yourself, your family and next generation, introspect and act against hate, to save nation and society.
