Let me make a suggestion:
Let us recognize this incident, whatever it may be, as part of legitimate PTI's right to political protest as long as it is not disruptive to other people's lives.
If the incident is truly so horrendous as some are claiming, then of course it will motivate enough people to come out in support of PTI and what it wants to achieve.
If this incident is overblown, then it will fizzle out by itself.
We have seen that happen multiple times before. Let PTI make yet another attempt, and we can wait for actual results this time as well.
Why argue with those whose minds are already made up?
