Have any philosophers given classifications for philosophy that could be "detached from reality" at least in current times?
For example, some platonist ideas are "pretty far out there".

Many people use the term pseduophilosophy by analogy with pseudoscience. This, however, is controversial, since there are no universally, or even widely agreed upon standards for what is a legitimate philosophy, as opposed to a pseudo one. The very use of the term, therefore, is considered by some to be a rhetorical device, a way of ridiculing a philosophy rather than disproving it or responding to it. (In contrast, "pseudoscience" is relatively easy and non-controversial to define, based on widely accepted standards for scientific legitimacy.) Part of the problem is that philosophy is cyclical, and long-abandoned theories can unexpectedly gain new currency in a way that is much less likely (but not unheard of) in science.
Some thinkers cited by Wikipedia as using the term are Christopher Heumann, Michael Oakeshott and Nicholas Rescher. In general, it is associated with the movement within analytic philosophy to make philosophy more rigorous and science-like.
It is also related to the "linguistic turn", and the assessment of certain longstanding philosophical conundrums as "pseudo problems," which are just the result of confusion in language, and not actual paradoxes. This is associated with the logical positivists, but it was inspired by the work of Wittgenstein.
