Romans 14:3  “Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.”
We’re big on talking about not harming a weaker brother, and rightly so.  But here all are admonished to treat one another fairly, regardless of the side of the issue you’re on.  Treat the weaker ones with kindness and compassion and the more experienced ones with respect.

13  “…but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother’s way”
Here is the word we use in reference to the weaker, but in the context it is to both sides.  However you look at something, remember it is all to the Lord.  Therefore, resolve to consider your brother in all things regardless of whether he is weaker or more experienced.

14  “I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself…”

20  “For meat destroy not the work of God…”

21  “It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.”
What are your intentions?  Whatever we do in word or deed, do for Christ.  Very easy to get legalistic with all of this.  As long as we keep love for Christ and love for our neighbor as our focus, we will be ok.  Each must carry his own load, and we must look out for the needs of others.  Always a balance.

23  “…whatsoever is not of faith is sin”
