Even the most basic fact checking shows many of they to be exaggerated, missleading or outright lies.
Lets look at two of the missleading examples:
"A janitor in Malmö was shot and sustained life-threatening injures while clearing snow in February 2017. Police detained several suspects, understood to be linked to gang violence, for questioning. A 15-year-old boy was arrested on suspicion of attempted murder."
Now following that link and no mention is made of faith or residence status, so its an assumption to link it to immigration, unless you still wish to pedal the myth that gang violence didn't exist in Sweden prior to immigration and that no ethnic Swedes are ever involved? Of course its doesn't discount that they may be immigrants, but the Gatestone piece makes no distinction and is wildly missleading.
Then we have this:
"Sweden's military forces have been drastically reduced since the Cold War. However, the authorities suddenly seem to have realized that there could be potential for armed conflict in the future. There are now plans to reintroduce compulsory military service."
Now in the first link Gatestone cite themselves (never a good sign) and the author is a known neo-nazi, the second link is true that they wish to introduce national service. The question is why? Here's the kicker, its got nothing at all to do with immigration, but rather is entirely to do with the treat Russia poses. As such maybe you can explain exactly why its even in a piece targeting Swedish 'no-go zones'? Oh that's right its just a Swedish government lie.
So in answer to your question, Gatestone is bad for a number of reasons:
- It has a track record of inaccurate reporting, up to the point of outright lies and highly missleading use of sources.
- It continues the use of articles written by a known neo-nazi, one they no longer have any ties with, but continue to use material from without explaining why they dropped her
- The bias of the articles and writers is quite clear, for example they only dropped Ingrid Carlqvist when she started to target Jews as well as Muslims. Which would illustrate a rather clear bias. Perhaps you can explain why they fail to mention this at all?
Now that's just a quick start of the top of my head, also of interest is the funding of Gatestone and similar sites, something I have asked about before and you seem determined to ignore.
