Are Taurus man and a Cancer woman a good match?

They're OK for fun, but longterm? No. Taurus's become to egoistic, Cancers much too sensitive for that. I'mma lay it flat out for y'all.
They have their "cuddly" "warm" moments as a normal couple together but when they're not physically next to each other they're strangers.

This match will work well.

Yes, but there are different Taurus and Cancer. It depends what your values are. Both are home bodies. Taurus desires emotion which Cancer has. Cancer desires romance and security which Taurus has. Taurus is playful and so is Cancer. Some Taurus are super sensitive and some are tough. Same with Cancer. I'm a Taurus and if I found the right one, I'd marry a Cancer with bias over all signs.

Why the need for strangers and Tooth Fairy science?

People should be judged as unique, individual persons, not based on what arbitrary group they belong to. To paraphrase Martin Luther King, Jr., a person should be judged not by the color of their skin -- nor the date and time of their birth -- but by the content of their character.

Yes

Nope.

Based on sun sign alone, yes. But you need to look at the entire charts of both people.

Good match.
