As with all issues of real import, there's no one-size-fits-all solution. It's a complicated issue. I recommend checking out this book for an accessible breakdown of how we've gotten here; it'll help give context and insight into the issue.
As an interested layperson, my best suggestions are:
To get an overview of the situation, reading "The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting Up a Generation for Failure" is a good place to start.
To briefly summarize a central point: we are teaching our next generation that the correct learning environment is through safe spaces and political correctness that protects you from "harmful" view points. These views might be as simple as the idea that enforcing the usage of gender pronouns is a bad idea, which was Jordan Peterson's crime that got him protested at Universities across Canada and the United States.
Regardless of your opinion of the facts of that particular debate, the more important point is this: it's now fashionable to tell someone they can't speak in an institution, if enough people don't like their ideas. And so we are not exposing people to "many different points of view" as you put it, so much as exposing people to "campus approved points of view".
PS - To everyone downvoting me without reading, you are quite literally proving my point about ideas being silenced instead of engaged with. So please continue, the irony is delicious :)
Don't know if you are interested in this but Jonathan Haidt (plenty of videos of his lectures on Youtube as well) talks about this and it's modern advent.

His big thing a lack of diversity in viewpoints is intellectually stifling. To kind of put his ideas in a nutshell: for example, an economics department should have liberal thinkers who border on marxist economic ideas just as much as they should have extremely conservative free-market types. Political science should have liberals and conservative viewpoints.
He wrote a really excellent book Coddling of the American mind about this and it's current expression in young people being intolerant of other viewpoints on college campuses.

TL;DR - you might be interested in Jonathan Haidt's stuff on why it healthy and important that opinions and viewpoints differ.
I think Texas might be a mistake, but I enjoyed Boghossian’s calling out of the bullshit factory at PSU.
We’re facing a nasty race to the intellectual bottom on the left. This is an excellent book on the subject that grew out of an essay in the Atlantic: https://www.amazon.com/Coddling-of-American-Mind-audiobook/dp/B079P7PDWB
The more recent case of one of the worlds leading experts being canceled from MIT because he believed ideas and people should both be considered on their own merit: https://www.theatlantic.com/ideas/archive/2021/10/why-latest-campus-cancellation-different/620352/
It’s hyperbole to compare these people to Jordan Peterson or other rightist provocateurs who have ideas that are actually bad. The real unbiased search for truth and understanding at universities and schools is being cancelled if it doesn’t fit a woke virtue-signally narrative.
The Coddling of the American Mind If you want to understand the right's legitimate grievances with the left, there is no better resource.
Please have your parents read, "The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting Up a Generation for Failure"
