Do you think that's a fairly mainstream view, or fairly niche?
I do feel like we may be very close to seismic changes in the world we know. A lot of things feel very fragile. Old unions, political certainties, people's incomes and standard of living. Lots of resentments and ill feelings doing the rounds, usually ends up with an outlet. Often not a good one.
Without checking I can tell you these will be people who are fairly old - close to if not past retirement age - hailing from more rural communities who did well or appreciated the sense of security that communism gave them. The speakers will likely be younger, political opportunists trying for a populist anti-EU or anti globalist agenda.
Most Czechs don't take the security benefits and increase in living conditions provided by the EU lightly and there doesn't seem to be much of an appetite for debating a Czech departure from either the EU or NATO.
But, we live in polarising times and Russia's ability to shape online debate and sponsor sidelined parties or individuals into positions of prominence is always there. My instinct is that the first Czech reaction against globalisation will come against poorly trained, low income migrant labour or along traditional ethnic lines before the more abstract political organisations or corporations that should be held to account.
