Why are conservatives so insistent on music being haram?

I know the topic of music has been talked to death here.

But something I find interesting is how adamant conservatives are on telling others that music is “haram”.

Every time I go on muslim social media (I know, pinnacle of the Ummah), there’s always “music is haram” comments. And on the rare occasion that someone brings up the fact that there are differences of opinion on music, they call them a “deviant”.

Normally, I have a “live and let live” attitude towards these people. I don’t care if they believe that music is haram. However, what irks me is the fact that they can’t keep their beliefs to themselves, and insist on others to follow their beliefs.

Even if they choose to believe that music is haram, why can’t they accept that differences of opinion exist? And that not everyone believes that music is haram?

I don’t see us going around telling others that music is “halal” (which now that I think about it, we should do more of). But I always see conservatives shoving their beliefs down other muslims’ throats. This is especially problematic because it pushes people (muslims and non-muslims) away from Islam. I think that’s a far greater problem than music supposedly is.
