If a person has a tattoo do you assume they were born with it? No, of course not. It’s something they decided to do to their body for whatever reason. It’s an artifice, it’s not “natural” but is it a lie? No, of course not. That example is so obvious, but it illustrates a point.
We all do things to our bodies to maintain health, improve our looks and express ourselves.
If you ask a woman “Do you dye your hair?” and she does but she says no, then she is lying.
If you ask a woman “Did you have a breast augmentation?” and she did but she says no, then she is lying.
If you ask a woman “Do you have makeup on?” and she does, but she says no, then she is lying.
Et cetera, et cetera.
If you feel that only “natural” beauty is “real” beauty that’s your business and like everyone you have a right to your opinion. But personally I wouldn’t blame anyone who is asked those sorts of questions for saying “None of your damn business”.
After all, why is it so important to you and why do you have to know? What a person does with their body is their right and why should they care if you feel deceived?
People don’t have to pass your reality meter. You have to accept them as they present themselves. You are allowed to like it or dislike it. You are allowed to think there is such a thing as “real” beauty and “fake” beauty. I find it rather silly and superficial of you to call it a lie and a deception.
Why don’t you try getting to know the “real” person. Look into their eyes and see beyond physical appearance. Enjoy the fact that it takes all kinds of people to make up this world. Some women like wearing makeup and some don’t. To each his/her own.
