We have to commit to metric, every inch of the way.
Anyway, from Wikipedia:
"During the most recent ice age (at its maximum about 20,000 years ago) the world's sea level was about 130 m lower than today, due to the large amount of sea water that had evaporated and been deposited as snow and ice, mostly in the Laurentide Ice Sheet. Most of this had melted by about 10,000 years ago."
Has this been under dispute?
One doesn't negate or minimise the other, nor is it the early signs of just a few cm's here or there that are the primary concern.
Also, there is serious evidence that this one is anthropocenic.
And finally, even if it wasn’t, our societies will be affected so much that it is a good investment to work on preventing it.
And finally - Earth had it’s periods when it had o2 contents so low that humans wouldn’t survive, ditto with co2 levels being so high at times that we would feel like in an extremely stuffy room at all times.
From 14,000 years ago to 6,500 years ago (pre-human), the sea level rose 110 meters. That's 14mm/yr.
From 1880-now (industrial era), the sea level rose ~0.2 meters. Thats 1.4mm/year, an order of magnitude less.
From 2006-2014 ("things are really bad!" era), the sea level rose 3.6mm/yr. About a quarter of how quickly they rose before there was any human intervention at all, yet people will still insist that this rise is due to human behavior.

Meanwhile, your argument is a non sequitur. Arguing that the sea level has previously risen faster without human intervention provides absolutely no argument against the fact that modern sea level rise is a result of human activity. We have evidence that the temperature is rising faster now than it has in the past 20,000 years (https://xkcd.com/1732/), curiously coinciding with the advent of the industrial revolution, and we understand well the mechanisms that have caused it and are still causing it.
You're afraid of change. That's understandable. I empathize. Hiding from the truth won't help.
Your comic book strip about temperature is more of a non sequitor than my historical data about the very trend under discussion could ever be.
And I’m not afraid of change. I welcome it with open arms. It’s the folks who doomsay about the climate driven end times who are afraid.
Firstly, XKCD is a comic, and its wrong about the temperature timeline. They completely skip over the Younger Dryas, which is very well documented: https://en.wikipedia.org/wiki/Younger_Dryas#/media/File:Youn...
(also note from this data, that the earth was warmer in the first half of the Holocene, we have been trending lower despite the recent mild increases)
Secondly, no we do not have evidence that it's rising faster than any time in the past 20K years. The end of Younger Dryas was a 20C increase in less than a couple hundred centuries.
Take a look at the sea level proximal data for the Holocene: https://en.wikipedia.org/wiki/Early_Holocene_sea_level_rise#...
The modern sea level rise is barely visible on that chart.
