Actually it is a wrong perception that Imran Khan or PTI has taught their supporters to use a bad language. If your reasoning is that it is due to IK using some offensive tone in the dharna, then MQM supporters should have been 100 times worse than the PTI supporter as Altaf not only uses an offensive tone like IK did but he even abuses people in his speaches. My take on the problem is that people who support/supported IK are those who are sick and tired of mega corruption by Sharifs and Zardari, and secondly because they have decided to protect each other. Peoples mental health gets a hit when they see how a few powerful are looting the country with both hands. People are getting frustrated and in some cases get a kind of depression if they watch too much TV. This frustration has increased many folds since we got privat news channels and so called free media. You will agree that listening to TV news in Zardari era of 5 years, with all those mega corruption cases in thousends of billions was nothing but a torture for any one who loves this country. Those who chose to support PTI, did it from only one reason. They percieve him clean and they want him because they hope he will stop this corruption and do some type of accountability.
In an ideal situation, I think people wouldn't mind having different parties with different ideas and different style of politics and they would like to discuss issues based politics as they do in the west. But what makes many PTI people so harsh is because they believe that status quo politicians are criminals and not politicians as they should be. So for them contest is not between two parties but between good and the bad.
That's why MLN media cell needs to answer corruption charges rather than just employing some people to visit some sites and make tit for tat comments which won't ever change some ones mind. At the same time MLN government needs to become transparent and stop playing muk muka on corruption with PPP. After all you know too that Sharifs couldn't have made an empire of 200 billion rupees abroad without earning that money first and paying taxes. Their taxes before PTI emergance are lesser than any grade one banker.
