It amuses me how people attack others for their likes or beliefs, because they really look silly.
It's perfectly fine to state your opinion, and it's also perfectly respectable, as long as it's done properly and you don't attack the opposite side, trying to force your own opinion over theirs.
However, attacking someone in particular, or some belief (call it fandom or non-fandom stuff, this opinion is in general) by doing stamps or art, or banners, without talking or debating face to face with that person that causes you such bother, is quite silly.
Not mention that the person that does this is the one that will appear in the bad light or fall out of favor with many others (probably their followers, probably their friends). Please note that I'm not talking about Deviantart only, this also includes Facebook, Twitter, Tumblr, etc.
It happens, and, while it upsets/enrages many people, I've, after a long time, found them fun and silly.
Now that I’ve said this, I want to share with you a few thoughts about the life that apply to the internet communities and users:
People tend to assume lots about personal life and about their likes or dislikes of others.
Assuming makes you invent unbelievable stories that only get you sick and many times they have no real basis.
People's lack of coherence. They like/support something, call others 'friends' and, at the same time, they attack the same things and persons in other forums.
My advice: Be yourself; be coherent with what you think and what you do. Don't love/hate things depending of the people that watch/follow you.
Do always your best.
If you do always your best (writing, drawing, designing, animating, etc.) you will never regret anything. And others always notice when you really put your effort and heart in the things you do.
Don't take it (anything) PERSONAL.
In the same way that someone wants to hurt you, that person hurts himself/herself. Then, the problem is his/hers, not yours.
Hope this little rambling helps you somehow. This is not directed to someone in special, but to all of you. These have helped me lots lately, and if they help you too, that would be awesome.
Please feel free to express your opinion here or sharing what you think is important.
See you soon, friends!
