Yes, that may be the case that they are not totally wrong about all aspects of issues they raise, problem is how they present them and with debate those issues can be looked at and what is the root cause. Many issues are often the effect of some overlooked issue and sadly by dismissing the first layer for whatever reasons and not listening and disseminating what they say so it can be broken down and addressed fairly. Well alas that only fuels them into an extreme direction even more, isolating groups in society into political tribalism that ignores the issues thru dismissal of any message other political tribes may gravitate towards.
This sadly only widens the gap between the political tribes and fuels the extremist aspects on both sides.
But putting the right message across to encapsulate and ring true with both sides without biasing it towards one side or another is a very nuanced skill. Take climate change - people can argue one side or another all day long. But ask them - do you like clean water and air and you will find both sides agreeing. From their you can push thru what is needed on the back of that point over saying we are doing this to tackle climate change. Same result, just politicaly more easily absorbed and equally shifts away from the whole - well their not doing anything so why should we mentalities. If anything you shift that self serving mentality onto your side as they will then think about their air and water quality that they breath and drink as well as their families.
You also moot the whole historical data when people will argue that during the dinosaur period it was warmer and other counter arguments to climate change as it is the here and nows air and water they breath. Also easy to point out that if you run a car engine in a closed garage that the air quality is not good for you - something anybody in denial will comprehend and have to accept.
But without listening and debating what they said, pulling it apart and getting to the root cause and addressing real issues in a way that all sides can accept. You just see the extremes growing wider and further apart and that is not healthy for either side.
Perhaps we should worry about "Social Change" more as the current approach is akin to sweeping under the carpet and pretending there's no dirt and how everything is rosey, even though the distorted landscape hints that it is not and that carpet over time will bulge and bulge if this direction is left unchecked.
