Starting a sentence with because
Solution 1:
This use of because at the beginning of the sentence is actually not against the rule. The sentence is just fine grammatically. The case when it would be wrong would be something like this "Why do I love chocolate? Because it's totally delicious." This sentence is wrong because putting that word at the beginning changes it from a sentence to a phrase. Because it is punctuated as a sentence (beginning with a capital letter and ending with a period), it is a sentence fragment, and thus bad grammar. <-- Yes, this last sentence is also good grammar.
