What is important, is the tilt from the vertical axis. Think on a beam of light, and for arguments sake, every beam of light is a foot wide. When that beam of light is aimed squarely at a surface, it covers an area a foot wide - but if you start to tilt the surface it's hitting, it suddenly covers a bigger area. So the energy it contains is spread thinner, less energy for a given area, hence it's cooler.
When we're tilted towards the sun, we have summer, and vice versa. Thick as I am the initial statement is flawed. If you change the angle of a,surface (the earth) to a fixed point (the sun) the distance of the sun will increase along the line of the surface. Thus changing the angle. So distance no matter how insignificant must play a part.

Also take into account the lower elevation of the suns trajectory across the sky during the winter months means that the suns radiative energy is shining through a greater thickness of atmosphere and associated crud/dust etc. Therefore more heat/ light is dissipated and its colder. This is also why the moon looks larger but darker in colour when it has first risen due to the magnifying effect of thicker atmosphere, just like looking at something under water from above the surface. Taking all of this into account leads us to the conclusion that somewhere over the rainbow, weigh a pie.
Its better to ask a stupid question than make a stupid mistake.

Mathematically your point is correct, but seeing how the maximum distance any point on earth can change with the angle in question (i.e. 23.5 degrees) is 1600 miles (the distance between the arctic/antarctic circles and the north/south poles), that's only 0.0017% of the Earth's 91-94 million mile distance from the sun.

if you were on the equator line and travelling exactly at right angles to the earths axis - about 1,040 miles/hour :lol.
