I’m not sure who you think constitutes the ‘silent majority’ or what they stand for.
I’m not necessarily one for ‘trendy agendas’ but the more ‘tolerant’ - for want of an infinitely better word - views as regards women’s rights, Gay rights, disability and racial discrimination which have emerged since the 1950’s were probably all initially dismissed as ‘trendy’ and ‘new fangled’.
Not everything that is modern is good and not everything that is old fashioned is bad but we have to stop chucking the proverbial ‘baby out with the bath water’ and strive for a fairer and more egalitarian society imo. Can’t see modern Conservatism doing that.
