A lot of unnecessary mudslinging has happened due to some people resorting to tired, dumb and debunked attacks on BD.
Some other members on the other hand have gotten quite excited, mistaking this staged even for real sentiments of Bangladeshis.
Let me offer a quick overview of the reality to help these people get a grip:
1. The general BD population do not like India at all due to its foreign policy, particularly watersharing disputes and general miserly attitude during negotiations.
China, on the hand, is viewed very favourably as their contributions to BD-China relations have been overwhelmingly positive. They have stood by BD in times of crisis, provided generous ToT in different fields and offered soft loans for major projects on easy terms.
Anyone with common sense would realise that this "massive" 20-person protest is staged by R&AW to offer the Indian population a false sense of security when everything else looks bleak be it relations with neighbours, communal relations or the economy. BJP is struggling for validation.
2. Bangladesh govt will never oppose China unless it hurts our interests for the above reason regardless of who is in power. People who bother to research BD-China relations are well aware of this.
3. China has a non-intervention policy whereby it does not take sides in conflicts. China will not intervene in the event of a BD-India war. Any aggression intiated by BD against India will therefore leave us fending for ourselves. Only a hypernationalist, out of touch idiot would recommend such an endeavour.
4. China will never invade India deep enough across the Chicken's Neck to reach Bangladesh; China would gain nothing from this other than fighting perpetual wars against Indian military and local Indian militias. China "involving Bangladesh" is out of question. We share no border.
5. The only scenario where Bangladesh will get militarily involved is where India tries to push military supplies across Bangladesh to NE.
