You are allowed to enter the traffic pattern any way you like. AIM
recommends entering on the downwind at a 45 degree entry. Traffic on
instrument approaches tend to enter the pattern using either a straight-in
approach or a circling approach. Straight-in approaches are very common for
VFR traffic as well. Either the 45 degree entry or the straight-in gives you
plenty of opportunity to see and be seen.

Entering the pattern by descending into the downwind makes it difficult for
high wing aircraft to see you. If you are a low-wing aircraft, you also have
trouble seeing all the traffic in the pattern. If there were an accident you
would have to explain to the FAA, the families of the people you killed, and
probably some attorneys and a court room why you did not use the recommended
pattern entry. Even if there isn't an accident you risk incurring the wrath
of local pilots who might have had to take evasive action.

Uncontrolled airports tend to be squirrel nests anyway. Nothing you can do
about it except keep a sharp eye out (and maybe arrange a little blanket
party for the most serious offenders). :-)
