Would you consider purple a warm blue or a cool red?

To me, It depends on the shade of purple

Yes.
Purple is not a single color. Maybe a spectrum analysis could answer this for a given instance of purple, but that's not my area of knowledge.
- Specifically, purple is not a wavelength, unlike red(s) at ~700nm and blue(s) at ~400nm.
  Purple is what human eyes see when the blue and red cones are both stimulated by their respective colours of light.
  
  I like that some people are so confident in their incorrect understanding of something that they'll downvote the correct answer.
  What you said is correct.
  
  Nope. Purple is a wavelength that partially triggers both the red and blue cones.
  The visual spectrum is continuous, not just three wavelengths corresponding to the three cones.
  The blue cones and the red cones are stimulated by purple light. It’s a mix of blue and red signals from the retina, but the light is a single wavelength that is actually purple.
  
  So what would be the color created by a wavelength of 550nm?
- Right, indigo is a color (_{425nm), violet is a color (}400nm), purple is typically a blend of colors.

  Fun fact: blends of colours are also colours.

"Would you consider the middle to be closer to one side, or the other?"
- obviously it is D-flat C-sharp sucks.

That's kind of like saying if 1 is 0 + 1 or 2 - 1

Yes

Depends on the shade! There are warmer purples that are closer to red, and cooler purples that are closer to blue

All colors have cold and warm variants and can work in surprising ways when used in color compositions.
- I’m not trying to be a jerk here, but what’s an example of a warm blue? I can’t imagine it.

Depends on the purple

Depends on what shade of purple
- Or what tint, or what hue.

It depends on the purple.

It's a different color, I consider it purple, my favorite part of the color spectrum. Purple can be made with both blue and red, but still is a completely different color. How would you consider water? Like liquid oxygen or wet hydrogen? Or just like water?

It's anti-green
- Anti yellow

I’m colorblind and purple is often just blue without any qualifiers.

Purple is a group of colours in between of blue and red, but unlike Indigo is leaning toward red (hot).

Is 0 nothing or the sum of all numbers?
- It doesn't even exist.

Finally some important questions!

Purple is a kind of red to me.
- There are a lot of shades that people call purple
- 😒

Cool red

Lukewarm purple?

purple

It depends on the definition of purple.
- purple is when your eyes are about to cry with joy

First one, then the other

Erm what?... That's a pretty bizarre question. Like asking if a fork is more of a spoon, or a butter knife. Purple is not a red or a blue, it's a mix of red and blue, not a discrete wavelength. Violet and indigo may look similar to it but, unlike purple, are discrete wavelengths.
If one has to answer the question, it depends on the red and blue used to make the purple.
- I think you're missing the point somewhat.

Depends on the context.

I consider it a cool color because I can usually wear it and look good, and generally cannot look good in warm colors. But never thought of it as a red or a blue just purple.

A secret third thing

Colors are very dependent on cultural context so if people would put their countries along with answers it'd be nice.
I personally think it's completely separate and not really comparable even though directly translated from Icelandic the color is "violet blue". From Iceland

Idfk, for me almost everything with visible blue in it is blue.

more like an ultra violet

Purple is red; violet is blue.
