Not necessarily, no. Support for murdering apostates can be low in countries with a majority Muslim population (Albania, Bosnia, Kosovo, Kazakhstan and Azerbaijan are all in the low single-digit percentage range, it's at 8% in Turkey), and the figures for minority Muslim communities in western countries might be comparably low.

Also note that supporting an action does not automatically translate to enacting such an action, but such a mindset is still problematic.

And as the cases of Bangladeshi atheists that have been hacked to death show, such things do happen. Generally, apostates probably know to keep their head down in places where it is an issue. The fact that you say you live in a place with a considerable number of apostates shows that it's likely not one where you are.
