I was reading a reflection by Monsignor Charles Pope concerning beliefs, philosophies, and God. He opens by stating that

There is a tendency in the modern age, at least in the Western world, to trivialize the human person. One of the ways we do this is to say, in so many words, that it does not really matter what a person thinks or believes.

This is by no means a new sentiment (in the sense of being unique to today), but rather has permeated the "modern" era. For example, writing about 100 years ago, G.K. Chesterton said that this was often the attitude of the day. He continued by writing that

“It is foolish, generally speaking, for a philosopher to set fire to another philosopher in Smithfield Market because they do not agree in their theory of the universe. That was done very frequently in the last decadence of the Middle Ages….But there is one thing that is infinitely more absurd and unpractical than burning a man for his philosophy. This is the habit of saying that his philosophy does not matter, and this is done universally in the twentieth century, in the decadence of the great revolutionary period.” (Heretics)
