No not at all, you will feel it if it gets too thin. Honestly people on BAF and BME dont always know the facts, you can ask around some more if you wish its your decision, but from having stretched my ears twice i would say you are fine, theres some other threads on here about piercing placement, you should search for them and see.
Also yes, it looks thin, but even if it gets risky up to a 0g or 2g, ill guarente you that it will be okay at least to a 6g or 4g without going on a limb

But im gonna stick with my you'll be fine comments. Legitly though its your decision.
