Can you? Yes you can, but here is the true question: SHOULD you? hmmm In general, If you have to think about it, the answer is no, you shouldn't.
Can you eat two donuts w/creamer filled coffee for breakfast followed by a loaded pizza and Coke for lunch and then a large piece of lasagne for dinner? Yes you can. Should you? Of course not. Watching what we eat is alot like watching what we say.... or post.
You can use the same rule for clothing choices. If you put something on, look in the mirror and wonder if it looks good or not... change clothes. It really doesn't look good or you just don't like it. Either way, don't spoil your confidence by wearing it anyway.
Freedom of speech allows you to say whatever you like. Does that mean you should? Not always. Just because you have a thought, it does not mean it is "share necessary". Be as silly or artsy or dark or bright or moody or crazy as you like, as long as it causes no mental or physical harm. If you have to ask yourself, should I or shouldn't I - the answer is you should not.
Photographers & videographers are also subject to this standard. Whether taking images by cell phone,creating clips for tv news, if you're writing for a publication or you are a photographer with a camera, it is your responsibility as a fellow human, to show restraint, no matter how "compelling" the image.
There may be fine line but it is not blurry. Should you take that image or post those words? What are you truly trying to accomplish... deep down, what is the reason? Your question will be clearly answered if you are honest with yourself and here in lies the true strength of a person's character.
You are strong because YouCan, but choose Not to.
Be elegant in your choices. Walk with dignity. Do no harm to yourself or others. gingersnaps web
