I don't think it's a straw-man argument. I think you are right but it is not the whole picture of course.
I think it has to do with a number of related issues like 'comfort zone', 'fear of change', 'fear of the unknown', 'loss', 'grief' which when I think about it has a lot to do with just 'change', 'something different'.
I find change uncomfortable.
It has been comfortable for me to be a member of this forum a few years, Becoming an active member has been uncomfortable. However in the process of the few days I've been active I, while being shaken out of my comfort zone, have learnt more about myself and a lot hasn't been comfortable yet, I think, being able to deal with that (without booze) is what I need.
