My parents were Reagan dems and apparently I ' m a trump Dem now , we aren ' t all that bad <| sep |> Ignoring people isn ' t a solution to their bad ideas . You need to explain to them and the people listening to them why their ideas are bad , or at least why your ideas are better why they should care . A combination of the above and letting bad ideas get some sunlight is enough to defeat them . People need to be exposed to all sorts of ideas so that they can form a baseline , and see truly bad ideas for what they are be able to think critically and understand what makes one bad or good in their own view . tlrdr ignoring or suppressing bad opinions and people leads to the very thing you ' re trying to prevent . It sucks , but you actually have to put effort in .
