"forced" isn't relevant.

The real world isn't as black and white as the following contrived situation
indicates, but I'm not "forced" to go contract some communicable disease
either, and yet they are still very much viral and infectious.  The fact
that I can choose to avoid them doesn't make them less so.

Or did I misread you?
