How?
I'll be the first to admit that us Muslims can, at times, be very harsh and judgemental of others who we deem to not be practicing Islam correctly (lifestyle choices, way of dress etc.) especially when it comes to reverts.
Just imagine if you're trying to get on your deen and you walk into your local masjid and are met with someone criticizing your appearance (clothes, hijab, tattoos, piercings etc.) in a harsh and unforgiving manner. Or if you grew up in a household where your family/elders preached one thing when it came to the deen and did another. If this happens time after time I can see why someone would eventually distance themselves from Muslims and eventually the religion. So that's why I said if you feel like your iman is becoming low because of this, you should consider finding a more welcoming community (i.e. T'aleef Collective) rather than totally abandoning your deen.
That's why Baba Ali (founder of Half Our Deen) who also happens to be a revert said he was glad that he found Islam before he found Muslims...
