Kind of seems disrespectful.

Nope. And appropriated pagan fertility festival.

There were already traditional seasonal holidays. Christians conformed the Jesus holiday dates to fit the seasonal holidays, which over thousands of years they have eventually replaced. That's why Christmas is only 2 days off from the winter solstice, and that's why evergreen trees are part of it. Easter comes days after the start of Spring, which is where the rabbits and eggs are coming from.

Embrace Extend Extinguish.

It's true for Christmas, but less so for Easter, as the crucifixion probably occurred around the Jewish holiday of Pessah, which is celebrated in Spring.

The superstition surrounding Friday the 13th is widely believed to stem from the mass arrest of the Knights Templar on Friday, October 13, 1307.

Easter is the name of a Germanic pagan goddess of fertility

Can't say that with any degree of confidence. "Probably" as you said. We can't say for sure what year, let alone what specific day.

The date of the crucifixion of Jesus was earlier than 36 AD, based on the dates of the prefecture of Pontius Pilate who was governor of Roman Judea from 26 AD until 36 AD.[221][222][223]

We don't know the year, but we know the probable part of the year. There's no certitude, but if we don't fall in hypercriticism, we have a wuite high degree of confidence on the fact that it occurred around 14 Nisan, so on the beginning of April.

Yes. But the date of Easter was decided far before Christianity reached Germanic territory, so it's not a sign that they borrowed the date, it's the other way around. Because Easter was on the month of Ēostre, they gave it this name.
