I didn't know that switches are looked down upon by many until I read this post and I concur with the "mindset" explanation. However it's not surprising that people's minds change a lot over time so it's not strange to be in one mood at a moment and in the other later.
Moreover, I don't even take it as serious as that so my view of being a switch is just like playing different positions when playing football. Sure many people have their favorite positions, but who says I can't play forward at times and defensive midfielder when I feel like so? As long as I'm just doing it for fun and my teammates are satisfied I don't think there's anything wrong with it.
