In Christianity’s churches, your name is your baptized name. If there is any discrepancy it must be solved by you, or your family, and/or your Priest in the early stage of your life so that you can obtain a good and correct name for the rest of your life. Generally, how a name is spelled correctly is not up for debate and therefore it is okay to give your opinion and nothing else.
I hate how people spell the name Aaron with two a's, that bothers me so much! (ugh) Personally I'm not a big fan of the name period but if I did I would like it spelled Erin. I think that is much better!
