Your statement can’t really be refuted because it makes no claims of fact and is not based on an intelligent or educated assessment of the situtation.
The idea that “we” were on the same path as the Nazis is simply idiotic. “We,” if by “we” you mean the United States, United Kingdom, and Canada, those being the countries largely involved in European strategic bombing in that theatre of war, were in no way on the same path towards extermination of entire groups of their own population, the way the Nazis were. It’s an absurd claim and suggests you don’t know anything about Nazism, a philosophy that is about as far from Western liberal democracy as you can possibly get. Nobody taking a serious and objective look at those countries in 1939 would conclude that they were on their way to setting up their own versions of Dachau. If that were true, why haven’t we done it yet? We won the war. What’s stopping us?
The reason the Allies didn’t bomb the concentration camps is that, to sum up a lot of little reasons, they were a little fucking busy at the time. The Allied emphasis was, for good reason, on destroying the ability of the Nazis to mount military resistance. The Allies were not ignorant or uncaring of Nazi horrors; we weren’t fighting them over nothing. The Allies, with good reason, wanted to devote military resources to causing the Nazi regime to cease existing, which - correctly, as it turned out - was the only way to actually stop Nazi atrocities.
Hundreds of thousands of Allied servicemen died stopping the Nazi regime. There are more Canadians buried over there, or blown to bits so there wasn’t even anything to bury, than I could even begin to count. Thousands and thousands of them died bombing the Nazis. We’re just a week past V-E day here, for fuck’s sake. Some people get it - once again, as they do every year, the Dutch were effusive in their gratitude for Canada’s part in liberating their country. But apparently all that blood and sacrifice isn’t enough for you. If we “didn’t care,” why did 43,000 Canadians die stopping the Nazis?
And as Sophistry and Illusion points out, the idea that it even would have been feasible to do is stupid. The Allies didn’t have the technology to accurately bomb targets at that distance (most of the death camps were at the extreme end of Allied bomber range; Auschwitz, Chelmno, Treblinka, Sobibor, and Belzec were all in modern-day Poland, not in Germany) except maybe if they’d tried broad daylight raids, in which case the losses to fighters would have torn the Allied bomber force to shreds.
