I have a tattoo on my side.because my grandpa used to tell me this "be not afraid". And the phrase "do not be afraid" is written in the bible 365 times. that's a daily reminder from god to live every day being fearless.
Your opinion does matter if it agrees with what God says, who He is, and His plan, or if it encourages or enhances another person's life; then your opinion matters A LOT! Your approval is not necessary, though.
