Azadre, you for sure aren't helping to avoid the dangers that you state.
if you have "alla akbar"
and
"Say: He, Allah, is One. Allah is He on Whom all depend. He begets not, nor is He begotten. And none is like Him" - Holy Qur'an 112:1-4
Ashhadu Alla Ilaha Illa Allah Wa Ashhadu Anna Muhammadun rasulu'Llah"
in your signature you should be very gentle in your post that is about a terrorist attack that accured today. Like "my condolence to friends and familiy.", and show that muslims are very helpful and compassioned.
You should NOT post your personal concerns about what impact this might have on muslims, thoes post can be made the rest of the year.
