In short:

1- The verses are either taken out of context or verses which were meant to be for a specific incident and then introduced as a general concept which is not true.

2- The political conflict going on in the world now is explained through religious context by extremists who claim to be Muslims or Islam haters who use that against our faith.

3- You can put some time and try to study with a local Imam in your area to learn more about some controversial verses in the Quran to clear such misconceptions.

Almighty Allah knows best.
