Feel free not to like him, but it seems very biased to assume a 17 year old cannot consent to sexual relations with a 23 year old, but a 18 year old totally can. In the Western world a big majority of people have their first sexual experiences in their teenage years. Naturally, age gaps happen.

On a further note, you might want to look up terms like ephebophilia, hebephilia and pedophilia before accusing people of being pedos. And neither does a victim need to be underage for a perpetrator to be molesting them, nor are child molesters necessarily pedophiles. The majority of child molesters has no pedophilic tendencies.
