Display post from custom post type

You need to add

'post_type' => array('post', 'opinion')

to your $normal_args array and maybe remove the meta_query?. Are you sure you have any opinions with a _custom_blog_enhome of 1?

Start from

$normal_args = array(
    'post_type' => 'opinions',
    'post_status' => 'publish'
);

and add arguments one by one and watch the results.
