Angry? I guess yeah. But hoenstly I would be more disappointed really.
Because at the end of the day, none of the people you mentioned can offer solutions to the highly complex problems and challanges we're facing today. What they do most of the time, just bashing the drum. But that's not helping. Like as we've seen with Nigel and Boris, who both chickened out of what they started. We also see this right now in the parliaments in Germany, where the AfD has done nothing put spouting populism without offering suggestions or solutions. Infact, a few of their representatives have laid down their mandadate due to the huge stress they had to endure. Politics is hard I guess, when you're not shouting from the sideline anymore.
Right now the AfD is also suffering from a serious issue with antisemitism inside their ranks.
You should thank Bundesnachrichtendienst for that, since there's more than 6000 dangerous salafists (2014) kept in check and daily monitored by secret services in Germany. I think it's only a matter of time when the shit will hit the fan.
There are more violent crimes against refugees and immigrants than there are crimes by refugees and Muslims on Germans though. Particiularly if you take a state like Saxony that has a muslim population of 0,4%. Of which many are also students and normal residents.
So I am rather worried about right wing populism and extremism in Germany which far exeeds those 6000 Salafis. And which are just as violent. Which doesn't mean that they shouldn't be observed. But if you consider that the number of Salafis who are also Germans (See Kurnatz), is relatively high ... well, there is not much you can do about it. You can't condemn people for something they might do at some point in their life. That's why terrorism is so difficult to fight without violating the personal rights of citizens. And I don't see that danger yet in Germany.
I think the fact that our government is very carefully trying not to generalize and fighting xenophobia is doing a lot more here to protect us from violent Muslims and radical Islam. Dividing people in groups and creating a sense of paranoia hasn't really done much in France in the recent years. Except for starting one debate after another what ever if mosques should be closed, and having more laws and surveilance etc.
You bang on about these statistics but you dont actually put them in your posts. Do they exist?
Can you read German?
Here is an article, which I posted earler in this topic about it:
Refugees responsible for tiny proportion of sex crimes in Germany despite far-right claims following Cologne attacks
Otherwise, there are tons of articles, but in German about the Bundeskriminalamt. If you're interested you could look for polizeiliche kriminalstatistik 2015 and 2016. They are available as PDF on google. Those are the official numbers. But I am not sure of what use they are to you, if you can't understand German.

It is no surprise that yes, crime has grown with the increase of refugees and asylum seekers, most of those crimes though are so called victim less crimes. Which includes crimes like illegal immigration, using public transportation without tickets, lack of identification papers and so on. Only a tiny number of delicts are serious. Like sexual assault, harrasment, rape, or even murder and so on. The statistics show that it is blown out of proportion. And that there is also a huge difference of crimes commited by refugees and immigrants and foreigners in general, which also includes tourists, like geting caught for vanadlism while being drunk.
