Yes, we do.

>Do humans dominate the biomass of Earth?
Yes, we do. https://www.pnas.org/content/115/25/6506 "the total plant biomass (and, by proxy, the total biomass on Earth) has declined approximately twofold relative to its value before the start of human civilization. "
>Still, I would point out that the "domination" of which you speak is less than 300 years in duration, with no certainty to last beyond 500 years.
The Cambrian explosion happened 500 million years ago. Photosynthesis is projected to last another 600. We've used all easily available complex elements, and extracted much more. It will all oxidize once were are gone, and it will not regenerate in this time period. Even if we are gone, our impact and legacy will outlive us, likely ensuring we are the last advanced civilization this world will produce.

We dominate. Arguments to the contrary seem to be an attempt to avoid responsibility.
Avoid responsibility? For what?
Are you sure that has happened?
Do humans dominate insects, fungi, and bacteria?
Do humans dominate the biomass of Earth?
If you limited the scope of your remark to mammals, fish, reptile and birds, I would understand what you are saying. Humans have excelled at habitat destruction. Still, I would point out that the "domination" of which you speak is less than 300 years in duration, with no certainty to last beyond 500 years.
