I honestly don't really like the idea. I like the concept of switching bodies.. but really - even if magically switched bodies with an FTM - I wouldn't be looking in the mirror at me anymore. I'd be looking at a stranger. I don't like that, it scares me a bit. No one would recognise me, or really be able to relate. The person I was would be permanently gone forever. No-one would see them again that knew me before the 'switch'. At least with a successful transition, you are still 'you', if that makes sense.
It won't come to those extremes anyway, because over the next hundred years - trans* people will gain equal rights with their cis counterparts. I predict a similar movement to that of the LGB and Women's movement from the 20th Century. Trans* people will be viewed as normal within society, and we will no longer be looked at with such disdain, such misunderstanding and discrimination from an ignorant public. Transitioning will be greeted with wide acceptance and the difficulties that face us today will not be an issue any more. ->-bleeped-<- will be studied extensively in school as a requirement - with no cissexism. Trans* people will be more prominent and influential in society.
Compare the acceptance of the LG community today with the 60s and 70s. There is far greater acceptance (at least in Western society) since then. Even though there are many issues for the LGB community to overcome in regards to equal treatment and marriage rights, they are in a far favourable position than the trans* people they claim to thoroughly support. We are misunderstood and discriminated against like no other. There is really no comparison between us and the LGB community.. We are still 30 years behind in regards to rights and equal treatment within our communities, within our nations, within the media etc etc.
