Watch yourself well, because some are almost acting and doing as a paramilitary/parapolice organisations, using every means in very perfid manners, planned, joint and both in short and long terms of execution, not to say what they would do to a convert. They are many and you are alone. They like stealth and longer term modes the best. It is common for them also to use sihr and ayn/hasad.
It is hard to prove, but such people do exist, even portrayed on mass media with some cases/organisations.
They love, because of recent popular support to present themself as victims viceversa.
Muslims are suffering in catholic majorities, especially where there were wars and where greater minority.
Where catholics are minority, they will say muslims oppress them or majorise them, but their politics, for example in EU are at least 10x more protected and outspoken.
They have religious relicts in every public institution in regions wgere they are majority(hopitals, posts, institutions of every kind...) and outcry that they are oppressed.
For example they recently want self autonomy despite the war crimes in Bosnia.
