A couple of days ago I began wondering where the lines are to define 'persecution' and couldn't answer that myself. So I had a search online and there isn't a one size fits all legal definition of it.

There is no internationally agreed definition of persecution. Open Doors’ methodology defines persecution as:
Any hostility experienced as a result of one’s identification with Christ. This can include hostile attitudes, words and actions towards Christians.
This broad definition includes (but is not limited to) restrictions, pressure, discrimination, opposition, disinformation, injustice, intimidation, mistreatment, marginalisation, oppression, intolerance, infringement, violation, ostracism, hostilities, harassment, abuse, violence, ethnic cleansing and genocide.
So there will be differences in what is perceived as 'persecution'.
