So your evidence for that claim is random people's anecdotes about seeing too many Sikhs around?

I'm surely a giant racist. Nobody falls for that stuff anymore. If you want to understand why our politicians are acting a given way, you look at their key coalitions. In this case, there is a direct cause between the PM defecting from a close relationship with India's PM Modi, and who he needs to show alignment to in response to a political crisis affecting that community.
