CO2 most definitely is toxic.
No, not in the slightest.

(Not very toxic, you can take a few
percent).
It's not toxic at all.
Thicko, it is toxic to the atmosphere.

toxic [ˈtɒksɪk]
adj
1. of, relating to, or caused by a toxin or poison; poisonous
2. (Medicine / Pathology) harmful or deadly
[from medical Latin toxicus, from Latin toxicum poison, from Greek
toxikon (pharmakon) (poison) used on arrows, from toxon arrow]

(Definition 2) CO2 is harmful or deadly to most animal life when
concentration in the breathing gas is excessive. Therefore, it is toxic.
Admittedly, not as toxic as a lot of other gases, including carbon
monoxide, but still toxic.

No, you are wrong. CO2 is not toxic. By your argument a pillow or a knife
ate both toxic.

CO2 is an asphyxiant, remove it in time and the subject recovers. It has no
long term metabic effect.

Relying upon a dictionary for medical knowledge, other than a medical
dictionary, is fraught with problems. Not least that dictionary compilers
have no knowledge of chemistry, toxicology or medicine.
