Personally it doesn't bother me to hear someone say he or she talks to a guide, deceased relatives, Spirit, God, or gods or herself. If praying, singing, dancing, drawing, meditating, yoga, Reiki, thinking, walking in nature or whatever helps a person center and balance himself, cool too. If someone said I prayed on this and I feel it is right for me then I wouldn't be concerned either.
It's when a person says, "God told me to do x, y, or z" that bothers me. My experience is that when people say that for one thing they tend to use it as reasoning to do other things that might not be very reasonable, fair, ethical, or right, and it can be a slippery slope. I can say God told me I am the next leader of the country and believe that, but it isn't a very big step from there to, "God told me this law or that law isn't right and therefore I am vetoing this bill or insisting this be done whether it takes away freedoms or not He said I have been sent here to change xyz to reflect His laws".
I just want my government leaders to not be taking directions from and believing that s/he is specially sent here to reshape things to fit his religious views. If I believe in astrology and I check my horoscope that is not a big deal, but if I decide I need to lead the US according only to what my astrologist told me about how I am chosen to lead the country into war and come out victorious or limit the rights of the people in some way, well that is a slippery slope too. I would expect a leader to listen to experts on topics, consider alternative options, think about what is best for the people in the US, do whatever centers her, and then act based on that instead of the idea that s/he is the chosen one and God told her it was the thing to do.
