Like I said, it’s not just what you said but the way you phrased your sentences, it came across as though you think very highly of yourself and you consider those, who sing a different genre than what you like, to be beneath you. Even though, many posters have already pointed out that opera is about a lot more than what meets the naked eye and that it is indeed very difficult to “perform” (not just sing) it well, you still keep making naive statements like oh yeah it’s not difficult and I could sing it at least as great if I wanted to.
Because you so boldly stated above that the only reason something you sing would turn out badly is if you had no interest in the genre to begin with, I am going to use your recorded song as a reference here. Good singing doesn’t just require passion and feeling. Skill and training are key ingredients to good singing.

Queen, you have a good singing voice. But honestly, this is a poor choice of song for you. In this case, even if you had perfect surroundings/mic/studio/whatever, you still wouldn’t have been able to do this song any justice.
You said so yourself that professional singers practice and train so much. I agree 100%. But I don’t agree that you need perfect setting to spot good talent. Trained singers can blow your mind just humming a few lines naturally without the support of musical instruments. You, my dear, need a lot of vocal training to build your range of pitch, breathing, and control.
