Why do many people claim they are enlightened when they are not?

So many new age thinkers , even from other religions are now engaged in lot of meditation, rituals and they say they are awakening and claim to be enlightened. But they don't actually fall into the category of the enlightenment we consider as Buddhists.

"Enlightenment is associated with the perfection of discerning wisdom into the Four Noble Truths, which brings about the cessation of dukkha (suffering; stress; dissatisfaction)."

"Attaining full "liberation" and "unbinding," meaning no longer being bound to the cycle of birth and death."

I have read Buddhist teachings which stated that this misconception can actually lead them to danger rather than to sugathi.

The reason why I am asking is (I don't mean to be judgmental here) I personally know of such people who totally view it and live it in a very different way such as having physical connections with more than one partner - because they believe in expanding love, loving more than one person , and being honest about it to the wife makes it "not cheating" .But still it is sexual misconduct. No matter how he/she views it.

And also there are some SPIRITUAL/LIFE COACHES and GURUS. Who misuse religious teachings and mislead their clients. Selling teachings to attain a wrong state of enlightenment.

Why so much of misconceptions in this new age? Any thoughts on this?
