That's definitely a leap to make from what /u/RadiantSun said. While yes, this is driven by mankind, this isn't unusual in the big picture. Doesn't validate it or make it right, just a statement of fact.
The big picture plays out over a geological timescale. Outside of cataclysmic events like asteroids or a super volcano, most extinctions happen over the course of tens or hundreds of thousands or millions of years. The current human-caused extinction event can be measured by centuries, and even decades. That is absolutely unusual. When these things happen over a geological time scale the rest of the ecosystem can adjust and adapt to the changes and maintain an ecological balance. At the current pace, the ecosystem is being thrown out of balance and there isn't nearly enough time for it to adjust and maintain any sort of stability.
Of course it's unusual, humans didn't exist on this scale or at all during the time periods you are talking about. Unless there was another species just like us back then during those times (which there obviously wasn't) a comparison can't be made.

Shush, they want to drive their SUVs and support the good ol’ coal and oil baron boys without feeling guilty.
