Probably not bad advice. Make sure you work out ALL the religion issues before you think about getting married. She'll want to get married in her church, and if you give in and do that, she'll expect your relationship to be centered around her religious beliefs. Because, after all, if you stand there in the church in front of a preacher and agree to all the God stuff in your wedding vows, then she'll expect you to agree to religion in your marriage. This means going to church with her all the time, baptizing your kids and raising them Christian, etc. Better to find out now that you won't be compatible rather than after you get married.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
