Are Hebrew/Hebraic Roots, Torah Observant Gentiles Making Themselves, “Twice the Child a Hell?”

Here's a serious question for my friends and those who are Hebrew/Hebraic Roots and Torah Observant gentiles:

Matthew 23:15 says, "Woe to you, scribes and Pharisees (the Rabbis of Today), hypocrites! For you travel across sea and land to make a single proselyte, and when he becomes a proselyte, you make him twice as much a child of hell as yourselves."

Here's the question:
In today's internet world where so much information is available, does it take an outside source like scribes and Pharisees to make someone "twice as much a child of hell" these days? Can't people do it to themselves?
