When you're a bhikkhu they'll not dare to criticise you to your face, if they are offended.
Anyway, in my experience laypeople often get offended at something or other, some petty thing; a monk laughing, or a monk walking too fast, or a monk who holds his bowl differently to how they have seen before. Laypeople even get offended at monks following vinaya as laid down by the buddha, instead of following distorted traditions from their home countries.
But the wonderful thing is, it's not your concern.
You just do your practise as a bhikkhu, and there will be someone to feed and house you. There wil always be sensible laypeople who will see beyond a mahayana tattoo, and instead see the earnestly practising bhikkhu.
saturated with joy,
you will put an end to suffering and stress.
