Author Claire Fox claims education and social policy has made students fearful of opposing viewpoints.
Her book, I Find That Offensive, discusses causes of what is becoming known as 'generation snowflake' - young people being scared of challenging ideas and disagreements.
And Fox claims political correctness has now gone too far.
“We’re all walking on eggshells, trying to avoid offending people," she told Julia Hartley-Brewer. "No matter where you go, somebody's going to say 'I find that offensive'."
The author finds the number of students who have agreed with 'no platforming' surprising. Almost two-thirds reportedly believe the National Union of Students (NUS) is right to have this policy, which means certain people and groups with racist or fascist views are banned from speaking at student union premises.
"These students who object to everything and are thin-skinned are socialised as mollycoddled kids in schools," Fox added. "It is education and social policy, with over-emphasis on safeguarding.
"It emphasises they are under threat and should be scared of everything."
The author, who is also the director of the Institute of Ideas which organises debates on controversial issues, believes this is a problem as people are raised with these beliefs. She claims this doesn't work in the real world, as we need to talk about issues.
"There's now horrendous headlines about how young people are suffering mental illness," she added. "If someone says a bad word to them or they're being bullied, they become fragile and can't cope.
"They become pre-loaded with all these anxieties by the time they leave school, and they can't cope when they come into this atmosphere of political correctness."
