You're arguing with people who only see the downside of nuclear power, but refuse to see any downside to other sources of energy. Here we see this for the carbon footprint, but it's also the case many other impacts:

Strip-mining for coal, devastating huge areas? This is fine.

Radioactive emissions from burning coal? Don't care.

Deaths caused by coal pollution and coal mining, compared to deaths caused by nuclear power? 'tis but a scratch.

Permanent problems with groundwater caused by decades of coal mining? Lalala I can't hear you.
