please don't presume a state of mind. a lazy response might be "obliviously complacent" and then we get nowhere. you could leave out the direct reference, such as "I think disillusionment is a bit dangerous, because..." (although you still need to tie in the relevance of such a statement) and still make a similar argument that better elicits a charitable response.
but that argument is presumptuous and fallacious as well. being disillusioned doesn't lead most peole to support single-party, state-controlled communism. being insulated and comfortable does lead to complacency and being out-of-touch however.
