As BJP is winning and forming governments in many states people who are interested to become politically active are coming and joining the party. As these people are not behaving formal training this may be having. Another aspect is that many members of other parties are also coming and joining this party. But their history is not been checked by the party. It is another reason for this type of behaviour I suppose.
Time and again, I have mentioned that any political party leader or worker should be very careful in today's world because it's so easy to record and quickly forward the images and videos like wild fire. They need to be toned down or the situation has to be defused quickly by the others around the leader or worker.
This looks like an embarrassment for the party, in a day or two we will hear a statement from the BJP spokesperson about the female BJP worker being rusticated or warned. But, we cannot blame the party for all such wrongdoings of people at the lower level because the high command cannot assess all the workers. I think the regional leader should take the onus to rectify such inappropriate behavior.
Honesty is the best policy.
