Not dangerous at all!!!
At the percentages we're talking about in terms of global CO2 levels in the atmosphere? Correct. Not remotely dangerous. One would actually say: Necessary.
Being willing to inhale a pollutant does not make it "not a pollutant".
it does make it "not dangerous" (not the "willing to inhale", but the actual amount of CO2 in the air), which is directly relevant to the statement you made.

Again. Not at the levels in the atmosphere though. Not even remotely close, in fact. What exactly do you mean by "amount of CO2 you decided to pick"? The amount I'm talking about is the same percentage that is creating hand wringing and calls for regulations. That amount is vastly less than anything even remotely hazardous to us in terms of breathing. If it wasn't, then we'd all be suffering from this all the time. We're not. So no... Not dangerous at all.

I apparently know more about the effect of CO2 on the air we breath than you do. You do realize that the "normal" level of CO2 in an interior space (like your living room) is between 350 and 1000 ppm (250 to 350 is "normal" for outside air)? The horrible rate that has everyone upset about is that the earth's rate in the atmosphere has on occasion in some areas risen to a super high... wait for it... 400ppm.
Over 1000 ppm, you might notice the air is a little stale. Over 2k ppm, a bit more. Over 4k ppm, you'll start to get headaches. And somewhere around 40k ppm, it's fatal. So yeah, if the concentration of CO2 continues to rise to a level that's like 100 times higher than the highest we've measured it since we've begun obsessing over the whole "OMG! Global warming!!!" thing, then maybe at that point, we might have an issue with the toxicity of the air caused by too much CO2.
It's not dangerous. The concerns about CO2 levels in our atmosphere have nothing at all to do with difficulty breathing it. It's entirely about the greenhouse gas effect caused by it. Which is a whole different thing. Hence, the issue with labeling it a pollutant to be tracked and regulated. That's a category generally reserved for things like oil spills in water, or a variety of complex chemical compounds that have actual toxic effects in the concentrations they are found in. CO2? Not so much.
