Whenever there is forceful support for an idea, ideology, group or anything else, no matter how good or bad it seems to be, opposition is inevitable.
Plus force brings about minus force.
One might not be aware what his right country does to another country, but another country might be. It’s the same with a person when he deals with other persons. One who acts only to support himself, his own intentions, ideas against others, will encounter analogous opposition
To be fair, both sides need to be understood and cared for. This way, opposition gets nulled.
Nothing justifies doing that for one side alone. And those who grant themselves the freedom to reduce another’s, reduce their own.
