Image of political activists

Is this the way dignified women behave?
The political activists should be careful about their public image, otherwise general public will feel repulsed by their activities, and it will be more difficult for common people to hold politicians in high esteem. Our political leaders should give instructions to recruit as their party members only men/women who have self-respect, not the belligerent ones.
Moreover, I do not know anyone who doesn't feel disgusted and think that our national wealth is being wasted whenever they see a bus or shop is burning. Destructive activities can make a political party unpopular. Therefore the political leaders should rein in their hoodlums during hartals, because peaceful demonstrations (e.g. the recent human-chain) are more effective.
