Joe Sugg has insisted soft young "snowflakes" are more easily offended than ever.
The "Strictly Come Dancing" star even claimed many youngsters would make "excuses" to get out of the armed forces in the event of a world war.
He told The Sun newspaper: "I wonder what would happen now if we had a world war. When WW2 happened, if you were fit and able, you were in the Army, regardless if you wan-ted to be or not.
"Now it would be interesting to see how people react to it and what excuses would be made to get out of doing something like that."
Asked about the so-called "snowflake generation", the YouTube vlogger - whose videos have more than 1.2 billion views on the website - admitted people's mistakes come back to haunt them, meaning he has to be very careful.
He added: "Now we live in a world where if you slip up once, you're going to have to pay the consequences your whole life.
"I feel we have to tread on eggshells so much now."
Meanwhile, the 27-year-old star has shrugged off the idea of a romance with his pro partner Dianne Buswell, 29, but he insisted he will stay in touch with the newly single dancer once their time in the competition comes to an end.
Asked if there was a chance of a relationship between them, he said: "No, I don't think so. I haven't got time. But after the show finishes we'll stay friends."
Dianne was dating "Emmerdale" actor Anthony Quinlan, and while they have gone their separate ways in an amicable break up, they "remain close friends".
Her rep previously said: "Due to their busy schedules and the distance they have separated but they still remain close friends."
