Well it's easy to see the worlds shifting tolerances.
In the past Atheism was persecuted against, it's without a doubt shifting towards the opposite. I mean there's many people on this site that are quite aggressively anti-religion. Someone posted on here that having a religious belief is "mentally infant". In class at the age of 14 my biology teacher was making fun of Christianity at the front of class. It's amazing how many people attack ALL religious people with sweeping statements of them being uneducated, ignorant or delusional.
The world is becoming more tolerant in some cases (LGBTQ, Ethnicity) but when it comes to religious beliefs it's shifting the opposite way.
I just avoid religious threads, but even then you can't avoid it. Going into a thread about a horrific tragedy like the attack in Nice only to leave with several users in that thread calling you (not directly) and EVERYONE who is religious "stupid", "delusional", "uneducated", "mentally infant" is unnacceptable.
