In Buddhism, is Escapism seen as a bad thing to take part in? In general in Buddhism, is escapism seen as a bad "movement" to involve one's self in? I have seen many posts on SE about separating one's self from one's body, or getting rid of desire, so; would these actions been seen as escapism?
Escapism does not address the core issue. Say you have X experience which you do not like and you distract yourself with Y experience with you take pleasure in. The solution is temporary as Y ends you are left unsatisfied again.

The case of much of the suffering are the unwholesome roots in craving, aversion and ignorance. Buddhist practice aims to remove them. 

Now let's take experiance you like. What happens is you think "Ah, I like this" hence the notion of I arises in your mind. Likewise with many forms of craving and aversions. So if you remove the craving or aversion by being equanimous (and also remove ignorance being aware of the arising and passing nature of phenomena) you stop perceiving a self. There is not separation of self from the body, it is just that you do not perceive a self as an entity. Also any perception of self is a concept or abstraction created by our mind which is never in tune with the true nature of what actually is there. Hence you have to get rid of any concepts about self (which in all cases will be wrong).
