I don't get the sense anyone's looking down on it, or criticising it/ them come to that, heck most all who work pay tax/ NI don't they..it's more to do with correcting the inaccurate notion many seem to have that there's this pot of their contributions from which their pension comes...More broadly, dunno why should you or anyone care about what others say/ think, guilt what even is that...good on you I say.
