Modi is very conservative, and has been targeting minority groups such as Indian Muslims and Sikhs. Unlike Muslims, who have a number of countries where they are the majority (Pakistan being a notable one, for good or ill), I haven't heard of one for the Sikhs. I don't claim to have a similar issue, but I can appreciate people wanting a homeland. I can also appreciate Indians in general not wanting their country split up (again). That in itself doesn't make people terrorists, imo.

From a Canadian perspective, that's like calling Quebec or Alberta separatists terrorists. Not really, until they start bombing buildings, kidnapping people, and otherwise inciting terror, such as the FLQ.
