"The scare quotes give an impression you have a problem with all science"
Not to me, it looks like the normal use of scare quotes. You could swap it with so called science. Stuff that people call science, which is not.
If someone doesn't like any science, why would they care about a distinction between science and so called science?
If you don't like that, then you don't like scare quotes at all, but then what's the problem with saying "so called blah"?
Using scare quotes like that makes me totally confused what you're trying to say. If it's
I'm simply criticizing what passes for science these days.
then why not say so. The scare quotes give an impression you have a problem with all science, not just bad science, which I don't think you meant.
For a discussion of how poisonous to meaning this practice of using scare quotes can be, see David Stove's chapter Neutralizing Success-Words, an analysis of leading 20th C philosophers of science doing it. http://nekhbet.com/popper/chapter-01.html part 3. It's extremely enlightening and pretty funny, as Stove always is.
