The controversial self-help guru was a featured speaker at something called Funnel Hacking Live in Orlando, a 3-day conference held by Russell Brunson ... aimed at boosting attendees' sales success by listening to motivational stories.

Of course, that's right up Tony's alley, but he used his time to mock science and the seriousness of the coronavirus pandemic, while firing up the anti-vaxxers in attendance by questioning the effectiveness of the vaccine.

Let's break it down -- first, Tony rips nighttime curfew laws in Australia by joking the virus only comes out at night. As most everyone knows, the curfew is designed to keep people from packing indoor bars and clubs and spreading COVID.

Next, Robbins pokes fun at the concern over the unvaccinated spreading the virus, when in reality ... the unvaccinated population largely accounts for the spread of the Delta variant and the lion's share of hospitalizations and deaths.

Finally -- like many others before him who have spewed false info about COVID -- Robbins equates it to other everyday risks like driving your car ... but makes up his own statistics to fit his narrative.

Tony claims 1,200 people die per day in the U.S. in car accidents, when the actual number is closer to 100 daily, while ignoring that more than 2,000 people have died from COVID every day over the past 2 weeks.
